Abstract

Method of moments (MOM) is applied extensively in electromagnetics, but the impedance matrix from MOM is so dense that it will consume prohibitive time if using the direct solver. In this paper, we will sparse the MOM-matrix using discrete wavelets transform method (DWT), and take the Daubechies wavelets of order N = 3 for example, introducing the theory of DWT and the construction of the transformation matrix. At last, we will provide a new example of a 2D conducting plate with a groove.
