A Study of the TM-TE Mode Conversion in Dielectric Waveguide Grating Structures

A design method of dielectric image-guide grating structures which are applicable for the millimeter-wave system is presented. A dielectric image-guide grating with notches in the sides and also another grating with notches in the top have been designed, fabricated and tested with TM-and TE-mode excitations. From the esperimental results the relatin between TM-TE mode symmetry in the grating structure has been investigated.
