Abstract:

Consider the scattering problem of grating numerical computer which was solved by an integral equation method. The uniqueness, existence and error estimate of the solution were analyzed. Numerical results show the advantage of the in
tegral equation method.

Key words: grating, quasiperiodic, polarization, Helmholtz equation, integral equation method
