Summary:
The paper presents a rapid analysis method of THz double elliptical mirror system based on the Gaussian beam (GB) expansion and tracking, working frequency at 119 GHz. Gaussian far-field pattern is firstly expanded into a series of sub-GBs making use of point matching (PM), then tracking GBs successively with specular reflection is to obtain near field and far field pattern. Synthesis results of mirror reflection, compared with Physical optics (PO), reaching to -60dB proves the correctness of the system modeling and analysis method.
