A Time-domain Macromodel for High Frequency Electromagnetic Field Coupling to A Single Transmission Line

a time-domain macromodeling algorithm based on the Analog Behavioral Modeling (ABM) in SPICE and generalized Method of Moment (MoM) is proposed in this paper for field-to-line coupling problems. The macromodel is derived through a fullwave simulation of MoM, then the extracted frequency-dependent admittance matrix is modeled using frequency-domain FREQ parts in ABM. Once the macromodel is obtained, it could be applied to arbitrary incident field and terminal loads, including the nonlinear ones, without the need of repeated time-consuming full-wave calculation and time marching method used for cases involving nonlinear loads.
