This paper presents a tutorial and overview of the Fast Multipole Method (FMM) which is used to improve the performances of the Partial Element Equivalent Circuit (PEEC) technique in the frequency domain. Aim of the tutorial is to introduce the reader with the basic theory of the Fast Multipole Method. Step-by-step implementations of FMM are detailed providing useful guidelines for the potential user. The FMM is used in the PEEC framework showing how to compute PEEC parameters in a more efficient way without compromising the accuracy. Several examples are presented in which FMM has proven to be useful. A comprehensive list of references is also provided to allow the interested readers to go deeper inside FMM.

It is becoming increasingly important to computationally predict, study, and prevent electromagnetic compatibility (EMC) issues arising within and between ICs and other components comprising portable electronic devices. Here, we conduct a phenomenological study involving an ultra high-resolution, threedimensional finite-difference time-domain (FDTD) model of a sample IC package having over one billion grid cells. Specifically, we determine the resonances and coupling patterns arising within the highly complex IC package. The frequency range of interest extends from 100 MHz to 7 GHz. Results indicate that the arrangement and geometry of the separate power, ground, and signaling networks comprising the IC package greatly influences the electromagnetic behavior within different regions of the package.

A numerical study for the electromagnetic detection of buried objects is presented. The whole GPR set-up is simulated through an integral formulation solved by means of the Method of Moments and a new discrimination process based on the 2D-Wavelet decomposition of computed electric field maps is proposed. The new wavelet methodology proves to be an effective tool for discrimination even in presence of noise.

This paper illustrates the possibilities offered by WIPL-D code to characterize the electromagnetic behaviour of Electromagnetic Compatibility (EMC) test facilities and to determine their optimal design. The test facility considered in this paper is the three-dimensional TEM cell, which was patented by INRETS in 2000. This paper aims to highlight the advantages of using WIPL-D code in the different development steps of this new test facility. The precision of the results given by WIPL-D code will be examined through experimental and numeric comparisons.
