An Efficient Solution for Volume Integral Equation Based on Meshfree Scheme

An efficient solution for volume integral equation based on meshfree scheme is proposed. The volume current is represented by a set of shape functions in the method of moments (MoM), where the shape functions are constructed on some distributed nodes without explicitly requiring continuity conditions, so that the basis function in this letter is not reliant on the tessellation and can be used with non-conformal meshes. Numerical results demonstrate that scattering from objects can be computed efficiently with the multilevel fast multi-pole method (MLFMM).
