Square Trihedral Corner Reflector Analysis using Wire-grid and MoM with Pulse Basis Functions

This paper analyzes the scattering characteristics from a perfectly conducting solid square trihedral corner reflectors approximated by wire grids using the method of moments and pulse basis functions. The accuracy of such analysis is evaluated by comparing its results with those obtained experimentally and numerically in other published works. Good agreement in the backscattering cross section calculation results is shown. The scattering characteristics of triangular and square trihedral corner reflectors are compared.
