A multimode equivalent network approach for the analysis of a "realistic" finite array of open ended waveguides

In this contribution we present a theoretical model for the analysis of finite arrays of open-ended waveguides mounted on finite mounting platforms or having radome coverages. This model is based on a Multi-mode Equivalent Network (MEN) representation of the radiating waveguides complete with their tuning and exciter elements and a high frequency description of the external region.
