Numerical Analysis of Low-Frequency Electromagnetic Scattering From Three-Dimensional Arbitrarily Shaped Conducting Bodies Using an Inductance Matrix

We have proposed a numerical method for calculating low-frequency electromagnetic scattering from three-dimensional arbitrarily shaped perfectly conducting bodies using an inductance matrix. The surface of the perfectly conducting scatterer and its apertures are modeled by a set of triangular patches. The current on each patch is computed by solving a coupled inductance matrix equation. Scattering from various conducting bodies with apertures is calculated to compare with the other methods. The proposed method well agrees with finite element method in electromagnetic field distribution
