Port Parameter Extraction Based Self Consistent Coupled EM-Circuit FEM Solvers

Self consistent solution to electromagnetic (EM)-circuit systems is of significant interest for a number applications. This has resulted in exhaustive research on means couple them. In time domain, this typically involves tight integration (or coupling) with field and non-linear circuit solvers. stark contrast coupled analysis linear/weakly circuits EM frequency domain. Here, one extracts equivalent port parameters that are then fed into the solver. Such an approach several advantages; (a) ports smaller than degrees freedom, resulting cost savings; (b) agnostic; (c) can be integrated variety device models. Port extraction tantamount obtaining impulse response linear system. deconvolution required effect unstable. Recently, novel was developed domain integral equations overcome bottleneck. We extend finite element method, demonstrate its utility via examples; significantly, we self solutions obtained using either fully or identical desired precision systems. shown within nodal network. also extracted data directly drift diffusion equation model physics.
