✦ Synopsis

Electromagnetic wa¨e propagation in two-dimensional dielectric gratings, consisting of a periodic array of rectangular anisotropic dielectric wa¨eguides, is examined here using an integral equation including the application of the moment method, the ¨olume equi¨alence theorem, and an adequate electric field expansion inside each rectangular dielectric wa¨eguide. Cur¨es of normalized phase constant as functions of the normalized Floquet's wa¨enumber are obtained for ¨arious wa¨eguide dimensions. Agreement is obser¨ed with existing results in the limit of the one-dimensional dielectric grating.
