Abstract
A fast frequency analysis of lossy substrate-integrated waveguides based on the asymptotic waveform evaluation (AWE) and Padè approximant technique in conjunction with the dyadic Green's function technique, is presented. The derivatives needed to evaluate moments in the AWE method are computed in a simple way thanks to an efficient method that reduces their computational cost. Numerical results demonstrate the efficiency and the accuracy of the proposed approachFile | Dimensione | Formato | |
