Analysis of electromagnetic scattering from a PCB inductor based on wavelet-Mom

Abstract

Inductor is a very popular device in various circuits. A PCB (printed circuit board) inductor makes its size more compact. When the signal frequency reaches to radio or microwave bands the radiation and scattering from it must be considered. Electromagnetic scattering from a PCB inductor is studied in this paper. Combining Mom with wavelet analysis sparsifies the matrix produced in calculation, which decreases calculation time and saves the computer sources. A Coifman intervallic scarlet on [0, 1] with level 6 is constructed for evaluating the current distribution on the PCB inductor wire. The current distribution and radiation pattern of a circular PCB inductor are given finally.
