Abstract

MoM is used in electro-magnetic field numerical calculation widely. Discretizing operator equation is a kind of effective method to solve electro-magnetic radiation. The advantages are stable and precise. But the formative discrete matrix is a dense matrix. To electrically large object, solving its inverse matrix is waste time and makes the whole calculation scope become huge. The article uses wavelet transformation to sparse its coefficient matrix in solving magnetic field integral equation. The method can reduce calculation time effectually.
