Hight order FD computation of TE and TM modes in single grid
No full textWe describe here a High Finite Difference Frequency Domain approach to the mode
computation in rectangular and circular waveguide with use of a single grid for both TE and TM
modes
Ridge waveguide optimization with PSO algorithm
No full textA technique of automatic optimization for guiding structures at microwave range is presented. Geometrical parameters have been optimized taking into account conflicting requirements (high bandwidth, high power handling capability and low attenuation constant) with PSO algorithm. Propagation performances are computed with a FDFD technique
Analysis and optimization of elliptic ridged waveguide with FDFD technique and PSO Algorithm
Full text linkA new design technique for elliptic ridged and sectoral waveguides is presented. The PSO technique has been employed, using FDFD to compute the propagation data of the guide. Conflicting requirements of wide bandwidth and high power handling capability are taken both into account with a suitable objective function
Enhancement of Cell Migration Rate Toward a Superparamagnetic Scaffold Using LF Magnetic Fields
No full textRecently developed superparamagnetic scaffolds for bone tissue engineering are still a complex object to deal with. Thanks to the possibility of controlling them remotely and directing therapeutic action in a non-invasive way, this work deals with the necessity of a clear definition and quantification of the field gradient, the forces and velocity it could exert on magnetic nanocarriers in a static magnetic field, and the heat and power generated when a time-varying field is applied, better defining the frequency response of magnetic nanoparticles entrapped in a solid matrix
