Abstract
Field profiles, equivalent isotropic radiated power (EIRP), beamwidth, and sidelobe levels of a quasi-optical power-combining grid amplifier structure are obtained using a whole-field electromagnetic analysis of a finite stru cture, This is efficiently obtained using a mixed spectral- and spatial-dom ain method-of-moments technique. It is seen that edge effects can have a si gnificant effect on system performance.
