Speed-up of PEEC method by using wavelet transform

The partial element equivalent circuit (PEEC) method has been applied for the time and frequency domain modeling of many different EMI problems. This method is especially suitable for the solution of problems which involve mixed circuit and electromagnetic parts as they occur in a VLSI system. An important issue for all modeling techniques is the faster solution of larger problems of this type. The makes the solution of more realistic EMC problems possible. We explore the application of the wavelet transform to the PEEC circuit matrix in both the time and the frequency domains. Further, examples are given for the speed-up due to the wavelet transform for both domains
