Fourier Modal Method

Despite its long history and popularity, to date the Fourier modal method has not been given a complete and concise coverage in the literature. This is especially true for one-dimensional gratings in conical mounting. This chapter is an attempt to fill the void. The emphasis of this writing is on completeness and clarity of the formulation, and the aim is to help a reader correctly and easily implement the method in a computer code, if there is such a need.
