Implementation of Three-dimensional Diffractive Gaussian Beam Analysis Method
This paper developed a 3-dimensional Diffractive Gaussian Beam Analysis (DGBA) method for the analysis of electrically large reflector antennas. Unlike a symmetrical 2-D structure, it adopts the approach of full plane expansion, where the illuminating field over the whole input plane is decomposed into a set of elementary Gaussian beams. These Gaussian beams are propagated to the reflector. Reflected beams are treated with Geometric Optics, while edge diffraction is modeled using the canonical problem of a 3D Gaussian beam incident upon an opaque Kirchhoff Half-screen. The output beam is a superposition of all reflected and diffracted elementary beams. The proposed analysis method is verified against a GRASP Physical Optics.
