Summary: Scattering of a Gaussian beam by dielectric cylinders with arbitrary shape is analyzed by using the moment method combined with multigrid method. The effectiveness of the multigrid-moment method is firstly shown from the CPU time and residual norm viewpoints. The effect of the initial value for the multigrid cycle is also considered. After that, the scattered fields by two dielectric convex lens are calculated and the effect of the radius of curvature, width and the distance between each lens on the scattered field is examined. | |||||
