Abstract :
An accurate theoretical approach for discontinuity problems in dielectric 3-D (rectangular) waveguides of open type is presented. The essential propagation mechanism of a mode on the 3-D structures is used to develop an improved 2-D model for which the radiation as well as the surface-wave transmission characteristics are derived. This approach takes account of the behavior of both surface-wave modes and continuous spectral waves, and is successfully applied in the design of image-guide grating filters. Experimental results are provided that prove the effectiveness of this approach.<>
