Fast Calculation of PEEC Macromodels using Frequency Derivatives∗

The accurate computation of partial elements plays a key role in ensuring the accuracy and the stability of the Partial Element Equivalent Circuit (PEEC) method. Inaccuracies in partial ele-ments computation, even at very high frequencies, may gener-ate late time instabilities. On the other side, accurate compu-tation of partial elements becomes prohibitively cumbersome when performed at high frequencies. In this paper a macro-modeling technique is applied, which is based on the use of frequency derivatives to allow a broadband characterization of electric and magnetic field couplings at a reduced computa-tional cost.
