Modeling of Anisotropic Magnetic Objects by Volume Integral Equation Methods
Keywords:
Anisotropic magnetics, augmented volume integral equation (A-VIE), method of moments, volume integral equation (VIE)Abstract
This paper presents the modeling of electromagnetic scattering from objects with magnetic anisotropy. We study the solutions of both the volume integral equation (VIE) method and augmented volume integral equation (A-VIE) method. For the VIE method, it is built from the 3D vector wave equation for electric field only. For the A-VIE method, it is built from 3D vector wave equation for both electric and magnetic fields. Numerical results show that the A-VIE method has better accuracy and convergence for magnetic objects compared to the VIE method.
