Interfacing electromagnetic structures and lumped nonlinear circuits

Abstract

In this paper, a procedure for the analysis of general electromagnetic structures, which include distributed regions and lumped sub-circuits, is described. The distributed regions are modelled by the Transmission Line Matrix method (TLM) while the lumped subcircuits are described by the State Space method (SS). The combination of TLM and SS methods yields a powerful approach that combines the versatility of SS and TLM. Neither approach on its own can solve such structures. The analysis is completely performed in the time-domain and there are no restrictions on the input functions or topologies.
