Abstract

This paper gives an overview on the design and analysis technique for quasi-optical systems developed at Queen Mary, University of London and Beijing University of Posts and Telecommunications (BUPT) in collaboration with Beihang University. The design and analysis technique in question is an integration of two numerical methods. One applies Gaussian beam mode analysis to transport signal beams between focusing reflectors while accounting for diffractive processes, the other computes the emergent beam fields of either transmission and/or reflection for signal conditioning components interleaved between reflectors. A three dimensional visual software is developed based on the integrated method. The paper also presents the experimental verification of this design and analysis technique based on a dual-path quasi-optical network.
