An Extended Version of Transverse Wave Approach (TWA) for Full-Wave Investigation of Planar Structures

An original transverse wave approach (TWA) is presented for full-wave investigation of planar structures in a periodic network. The introduction of a novel surface impedance sub-domain in TWA offers a natural framework for the implementation of complex planar circuits with simple layer. The simulation results given by our new electromagnetic software developed under C++ environment are in full agreement with the literature.
