A class of exact and higher-order surface boundary conditions for layered structures
No full textA class of exact and higher-order surface impedance boundary conditions (HOIBC's) is derived. Initially, exact impedance boundary conditions (IBC's) are derived first in the spectral and then in the coordinate domain. It is shown that in the coordinate domain they are expressed by a dyadic operator acting on the convolution product between the scalar Green's function, corresponding to the considered structure, and the tangential magnetic field. Next, it is demonstrated that the higher-order impedance boundary conditions in the spatial domain correspond to an appropriate expansion of the mentioned convolution product in the space domain. Finally, the accuracy of the HOIBC's is estimated by comparing the exact solution with that obtained through the HOIBC's for some typical canonical problems. The corresponding error curves presented refer to the worst error situation for each one of the chosen cases
TRANSIENT ANALYSIS OF RADIATED FIELD FROM ELECTRIC DIPOLES AND MICROSTRIP LINES
No full textThe transient response of the field radiated from electric dipole sources and microstrip lines, having an arbitrary time waveform is analyzed. By using the three-dimensional Fourier transform of the spectral dyadic Green's function, relative to the integrated structure, an analytical closed-form solution is obtained and equivalent circuits for the analysis of the transient phenomena in the far-field region are derived. Numerical examples are provided to obtain noticeable insights to the behavior of planar circuits working under Gaussian pulsed excitation
