Recently the refractive index can easily be controlled to make the periodic structures such as optoelectronic devices photonic bandgap crystals frequency selective devices, and other applications by the development of manufacturing technology of optical devices 1. Thus the scattering and guiding problems of the inhomogeneous gratings have been considerable interest, and many analytical and numerical methods which are applicable to the dielectric gratings having an arbitrarily periodic structures combination of dielectric and metallic materials 2. In this paper, we proposed a new method for the scattering of electromagnetic waves by in- homogeneous dielectric gratings with perfectly conducting strip using the combination of improved Fourier series expansion method 3 and point matching method 4.
