Replication Data for: Impact of conductivity on Lorentzian and Fano resonant high-Q THz metamaterials: Superconductor, metal and perfect electric conductor
No full textHigh temperature superconductors have created exciting opportunities for switchable metamaterial and plasmonic devices operating at terahertz frequencies. In recent times, there have been several demonstrations using superconducting metamaterials, such as thermal, electrical, magnetic, and optical switching. Here, we explore the impact of conductivity on terahertz metamaterial resonators with different resonance line shapes. Lorentzian and Fano line shaped resonators show different levels of enhancement in the quality factor and resonance intensity for metallic, superconductor, and perfect electric conductors, due to the interplay between the radiative and the non-radiative loss

Steady State Analysis of Three-Phase Self-Excited Induction Generator
No full textUse of an induction machine as a generator is becoming popular for the harnessing the renewable energy resources. Reactive power consumption and poor voltage regulation under varying load are the major drawbacks of the induction generator. The analysis of steady state performance is paramount as far as the running conditions of machine are concerned. To study the steady state aspects, we require methods by which the generator performance is predicted by using the induction motor data so that the effect of the basic parameters can be assessed. Having identified these it is essential to estimate correctly the magnetizing characteristics and related air-gap voltage under different flux conditions. Different methods are available to identify the steady state quiescent operating point under saturation for a given set of speed, load and excitation capacitor. These methods determine the saturated magnetizing reactance and per unit frequency. The operating air-gap flux can be then obtained by simulating zero rotor current conditions or a synchronous speed test. For its operation, the induction generator needs a reasonable amount of reactive power which must be fed externally to establish the magnetic field necessary to convert the mechanical power from its shaft into electrical energy. The NR method, a conventional method used for several decades to analyze the steady state performance of SEIG but it has some limitations. The genetic algorithm which is based on natural selection process and survival of fittest theory has several advantages over conventional method. The thesis work presents a steady state analysis of SEIG with a resistive and resistive–inductive load at various power factor using both NR and GA methods. Both simulated and experimental results are compared to examine the performance under various loading conditions. Both NR and GA simulated results are compared and performances with GA results are found to be slightly improving as compared to conventional NR method as far as the voltage regulation and loading is concern
Replication Data for: Dual-surface flexible THz Fano metasensor
No full textSensing technologies based on terahertz waves have immense potential due to their non-destructive, transparent, and fingerprint spectral response of several materials that are opaque to other parts of the electromagnetic spectrum. Terahertz metasensors reported so far merely exploit the fringing electric field on the top of the subwavelength resonators. Here, we experimentally demonstrate an ultrathin flexible terahertz metamaterial sensor on a low refractive index substrate which enables sensing of analytes from the top and bottom surfaces of the metamaterial, opening up avenues for dual-surface sensing of analytes with fringing resonant fields on both front and rear sides of a metasurface. Since most of the real-world objects have 3D curvatures, the reported flexible metasensor with large mechanical strength and stability in free space would be an ideal platform for ultrasensitive sensing of dielectrics, chemicals, and biomolecules of extremely low concentrations with dual non-planar surfaces
Encapsulated oil powder: Processing, properties, and applications
No full textThis review aimed to evaluate the applicability of microencapsulation of different oils (such as fish oil, sunflower oil, soyabean oil, palm oil, flaxseed oil, sesame oil, virgin coconut oil, and rice bran oil) by freeze drying, coacervation, fluidized bed coating, extrusion, and spray drying. Microencapsulation is the process of creating a functional barrier between the core and the wall material to avoid chemical and physical reactions and maintain the biological, functional, and physicochemical characteristics of the core material. The use of microencapsulated oils (oil powder) in food products provide a significant application in enhancing their functionalities due to the functional benefits of oils. However, utilization of simply oil leads to oxidation and other reactions causing deterioration of finished products quality. Microencapsulated oil has good oxidative stability, thermostability, shelf-life, and biological activity. Also, microencapsulation helps control the volatility and release properties of essential oils. This review focuses on the role of microencapsulation in increasing the stability, functional properties, and benefits of oils in various food products. Practical Application The comprehensive review on oil powder will be very useful for developing convenient and easily usable oil powder. The oil powder developed will have longer self-life, stability, and better health benefits. Oil powder can be used as a fortification in meat, dairy, and bakery products to enhance the nutritional value, fatty acids intakes, mouth feel, and textural properties. Such work will help the academic field as well as the industries to develop food products
Replication Data for: Photoswitchable Anapole Metasurfaces
No full textNonradiating charge-current configurations have attracted attention in photonics for the efficient localization of the electromagnetic fields. Anapole mode is a unique nonradiating state of light induced by the interference of electric and toroidal dipole that possesses rich physics with potential applications in micro-nanophotonics. Active control of an anapole is essential for design and realization of tunable low energy photonic devices. Here, we experimentally demonstrate an active anapole metamaterial device as a switch for the terahertz waves. The metadevice consists of planar resonators with photoactive inclusions of silicon patches in a hybrid metal-semiconductor configuration. The active element enables dynamic control over the contributions of the multipoles that eventually determine the formation of the exotic anapoles that hosts extreme nonradiative confinement and its active switching into sub-radiative Fano resonance and highly radiative electric dipoles. We further demonstrate two orders of magnitude change in the near-field intensity of the anapole that leads to 201% extinction modulation. The anapole metadevice provides a platform to efficiently control both the far-field radiation and near-field enhancement in metaoptics, promoting active micro-nanophotonic devices for potential applications in terahertz modulators, lasers, filters, and dynamic near-field imaging
Replication Data for: Accessing the High‐Q Dark Plasmonic Fano Resonances in Superconductor Metasurfaces
No full textSuperconducting metamaterials at terahertz frequencies has provided a platform for designing switchable plasmonic metamaterial devices. However, since metals at terahertz frequencies are excellent conductors, the superior role of superconductors in designing low‐loss, high quality factor metamaterials remains unclear. In this work, a low asymmetry Fano resonant split‐ring‐resonator is considered in which a regime of extremely low radiative loss is identified where the high temperature yttrium barium copper oxide superconductor meta‐atom supports a sharp high quality factor Fano resonance while an identical metallic resonator does not show the resonance behavior. The radiative and the nonradiative losses are comparable in low asymmetry Fano resonant meta‐atoms. The observation of high quality factor Fano resonance behavior clearly establishes the utility of superconductors over metals in designing lower loss plasmonic metamaterials at terahertz frequencies that may have multifunctional applications in areas that require strong light–matter interactions
Replication Data for: Ultrahigh‐Q Fano Resonances in Terahertz Metasurfaces: Strong Influence of Metallic Conductivity at Extremely Low Asymmetry
No full textFano resonances in metasurfaces are important due to their low loss subradiant behavior that allows excitation of high‐quality (Q) factor resonances extending from the microwave to the optical regime. High‐Q Fano resonances have recently enabled applications in the areas of sensing, modulation, filtering, and efficient cavities for lasing spasers. Highly conducting metals are the most commonly used materials for fabricating the metasurfaces, especially at the low‐frequency terahertz region where the DC, Drude, and perfect electric conductivity show similar resonant behavior of the subwavelength meta‐atoms. Here, it is experimentally and theoretically demontrated that the Q factor of a low asymmetry Fano resonance is extremely sensitive to the conducting properties of the metal at terahertz frequencies. Large differences in the Q factor and figure of merit of the Fano resonance is observed for perfect electric conductors, Drude metal, and a DC‐conducting metal, which is in sharp contrast to the behavior of the inductive–capacitive resonance of meta‐atoms at terahertz frequency. Identification of such a low asymmetry regime in Fano resonances is the key to engineer the radiative and nonradiative losses in plasmonic and metamaterial‐based devices that have potential applications in the microwave, terahertz, infrared, and the optical regimes
Replication Data for: MoS2 for Ultrafast All‐Optical Switching and Modulation of THz Fano Metaphotonic Devices
No full textIn recent years, the stunning performance of transition metal dichalcogenides (TMDCs) has been utilized in the area of field effect transistors, integrated circuits, photodetectors, light generation and harvesting, valleytronics, and van der Waals (vdW) heterostructures. However, the optoelectronic application of TMDCs in realizing efficient, ultrafast metaphotonic devices in the terahertz part of the electromagnetic spectrum has remained unexplored. The most studied member of the TMDC family, i.e., MoS2, shows an ultrafast carrier relaxation after photoexcitation with near‐infrared femtosecond pulse of energy above the bandgap. Here, this study investigates the photoactive properties of MoS2 to demonstrate an ultrasensitive active switching and modulation of the sharp Fano resonances in MoS2‐coated metamaterials consisting of asymmetric split ring resonator arrays. The results show that all‐optical switching and modulation of micrometer scale subwavelength Fano resonators can be achieved on a timescale of hundred picoseconds at moderate excitation pump fluences. The precise and active control of the MoS2‐based hybrid metaphotonic devices open up opportunities for the real‐world technologies and realization of ultrafast switchable sensors, modulators, filters, and nonlinear devices
