Parallel plate waveguide with radiating slot modeling using two dimensional frequency domain transmission line matrix method

Abstract

A two dimensional frequency domain transmission line matrix method (TLM) is used to model a parallel plate environment (or power-ground plane) with a slot which radiates into free space. A simple method of moments is employed to model the slot radiation in conjunction with TLM. A via wall waveguide with a slot is used as a test vehicle and results are compared to measurements.
