Abstract
A method of determining electrical parameters of inductive elements includes a novel technique of inverting an impedance matrix representative of said inductive circuit element. The method reduces model simulation time by a factor of 3000. In one embodiment, simulation time of a device model was reduced from 1 hour to less than 3 seconds. The method is suitable for use with circuit element modeling tools, circuit simulation environments, and antenna modeling systems. The method may be applied to inductors, transformers, antennas, etc.
