Summary:
This paper presents a fast solution to the electromagnetic scattering by large-scale 3D dielectric bodies of arbitrary permittivity and permeability. The scattering problem is characterized by using combined field volume integral equation (CFVIE). The CFVIE is formulated in the volume of the scatterers by considering the total electric and magnetics fields as the sum of the incident wave and the radiated wave of the equivalent electric and magnetic volume currents. The resultant CFVIE is discretized and solved by using the method of moments (MoM). For large-scale scattering problems, adaptive integral method (AIM) is then applied in the MoM in order to reduce the memory requirement and accelerate the matrix-vector multiplication in the iterative solver. The resultant method has a memory requirement of O(N) and a computational complexity of O(N logN) respectively, where N denotes the number of unknowns.
