In this paper, a fast analysis of scattering of dielectric shells is present. The calculation was done by using E-field/H-field integral equation plus method of least-squares rather than using combined field integral equation. Calculated results shows that this method possesses advantages of good accuracy and convergence
It is well known that either the electric field integral equations or the magnetic field integral equations have been widely employed to analyze electromagnetic scattering of conducting bodies. At some discrete resonance frequencies, however, when E-field integral equations or H-field integral equations are applied to attack this problem, the solution to method-of-moments matrix will be nonunique...
