Abstract

A method to validate the accuracy of method of moments (MoM) for arbitrarily shaped targets was proposed. Based on equivalence principle, integral equations for dielectric objects were established. The non-radiating property of incident sources was derived by setting the medium on both sides of the interface the same. According to this property, the accuracy of MoM for arbitrarily shaped targets can be investigated. Numerical experiments were conducted on sphere and octahedron targets. It is validated that among three singularity treatments, nabla operator transfer and coordinate transformation perform better than extraction in terms of accuracy. The results also show that the proposed method is possessed of applicability and generality.
