A dielectric waveguide antenna for X-band is designed. A printed dipole fed by a coplanar strip excites the Ex11 mode inside the dielectric waveguide. The waveguide mode in its turn excites a properly dimensioned patch, which generates the radiation pattern. Simulations are conducted from the stand-alone waveguide up to the complete structure to reveal the coupling and scattering effects between the...
The impulsive electromagnetic response of a thin metallic coating on a dielectric half-space is analytically investigated. Both TM- and TE-polarized electromagnetic fields in the configuration are excited by an impulsive line source. The problem is solved with the help of approximate thin-film boundary conditions and the Cagniard-DeHoop technique. Closed-form space-time expressions for electromagnetic...
In this paper a new technique is presented to evaluate efficiently the Green's functions of filament sources radiating over a half-space. The technique is based on the annihilation of the asymptotic and branch-point singular behaviours of the spectral Green's function. The asymptotic and singularity terms are subtracted, then calculated analytically and finally re-added to the remaining integral....
