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.

ABSTRACT: Dichroics are key components in the design of quasioptical networks.However, there are many practical issues in designing and fabricating these components. This article presents the design and uncertainty analysis of a dichroic being operated in a two-channel multireflector quasioptical network. The dichroic is designed to work as a frequency filter, which transmits at 54 GHz and reflects at 89 GHz. A low insertion loss is achieved both in simulation and in measurement. © 2010 Wiley Periodicals, Inc.

ABSTRACT: Diffracted Gaussian beam analysis (DGBA) is a fast method for Quasi-optical systems analysis, and Periodic Method of Moment (PMM) is an efficient method for analyzing Frequency Selective Surfaces (FSS). This paper introduces a 3D design software for Quasi-optical systems namely SiMatrix based on the integration of the DGBA and PMM. The SiMatrix offers the functionalities of visualized 3D modeling, systematic simulation and built-in post-processing. Those functionalities greatly facilitate the design and analysis of a Quasi-optical system.
