The paper is devoted to a preconditioned \texttt{GMRES} method to solve linear systems arising in cavity calculation of transverse magnetic and transverse electric problems. The authors develop new preconditioners based on fast transforms and Toeplitz solvers. The numerical results show that the method is very effective, especially when used in solving large cavity problems with large wavelengths.
