Zusammenfassung:Full-wave analysis is traditionally performed in the frequency domain, or in the time domain using specialized simulators (e.g., finite difference time domain). We describe here an approach that allows us to generate full-wave models for SPICE simulation. The advantage of this approach is that it allows us to easily consider the effects of arbitrary terminations. A frequency-domain finite-element method or method-of-moments solver is used to determine the frequency response of a three-dimensional structure, and then a SPICE model is constructed, which matches this frequency response across a specified frequency band. Some examples are presented to demonstrate the efficacy of the technique.
