Harmonic Balance Domain Decomposition Finite Elements for Nonlinear Passive Microwave Devices Analysis

摘要

Full-wave analysis of the time-harmonic field originated in waveguide devices containing nonlinear materials, possibly anisotropic, is addressed in this article. The approach combines finite elements and harmonic balance handling the nonlinearity via either Picard or relaxed iterations. To speed-up computation, domain decomposition is exploited to restrict the iteration to a small subdomain.
