Abstract :
A three-dimensional Diffractive Gaussian Beam Analysis approach for analyzing quasi-optical multi-reflector systems is presented. The illuminating field over the whole input plane is analyzed into a set of elementary Gaussian beams. These are propagated to the reflector. Geometric Optics initially treats reflection, while edge diffraction is modeled using the canonical problem of a 3-D Gaussian beam incident upon an opaque Kirchhoff half-screen. The output beams can again be expanded into a set of Gaussian beams. The proposed analysis is verified against a GRASP Physical Optics of a multi-reflector antenna system.
