Modal theory for diffraction from a dielectric aperture with arbitrarily shaped corrugations

The multilayer modal method is applied to solve the problem of scattering from a structure consisting of dielectric zones of constant refraction index in the aperture of a perfectly conducting screen. Adjacent zones are separated by arbitrarily shaped interfaces which are approximated by steps, form...
