Abstract: The generalized image method (GIM) was presented to deal with the electromagnetic scattering from anti-symmetric objects. Combined with numerical methods, it can-make the required storage and CPU time to be greatly reduced. The method was thoroughly studied in two dimensional problems and some numerical examples were given. -
