Circuit Level Modeling and Computer Aided Design Tools for Millimeter-Wave Quasi-Optical Systems

摘要

This report documents the development of of a number of techniques for thecomputer aided analysis of quasioptical power combining systems. The major results of the project were the development of models for IMPATT diodes suitable for harmonic balance analysis and transient analysis; the development of quasioptical Green's functions for cavity resonators and grid systems; the development of a Method of Moments code which can use the mixed scalar potential and vector Green's function developed for quasioptical systems; a transient analysis engine for quasioptical systems and developments of an harmonic balance technique suitable for quasioptical systems. The work makes a broader contribution to the computer ailded engineering of microwave and millimeter wave systems with complex device field interactions.
