MoM-based numerical analysis of a wideband rectangular to square waveguide transition has been presented in this paper for X-band orthomode transducer applications. Four cavities and two waveguide sections have been used to model the network. Derived frequency response has been compared with CST Microwave Studio simulated data to verify the analysis. Input and output aperture field distributions have been obtained to analyze the effect of higher order modes on aperture field distribution (for port 1 excitation).
