Abstract :
The optimization of the coupling tapers for an arbitrary transmission-line (TL) network, under obliquely traveling plane wave excitation, gets much less computationally cumbersome with use of a semi-analytical approach. The tapers are divided into numerous parallel-plate components and thus only the TL structure requires numerical simulation. The proposed approach has been validated for exemplary TL structures and various incidence angles.
