Abstract :
We are concerned with the design of inhomogeneous, all-dielectric (lossless) periodic structures which act as filters. The problem can be treated as an inverse problem. The authors begin by discussing scattering from a dielectric grating. The theory is used in the design of guided mode resonance filters.
