Y Dielectric Waveguide for Millimeter- and Submillimeter-Wave

A new type of waveguide structure having Y cross section is presented and investigated theoretically. This waveguide is suitable for millimeter- and submillimeter-wave and facilitates supporting the waveguide with little field disturbance. Numerical results are presented for the dispersion characteristics, the transmission losses, and the power distributions using the generalized telegraphist´s equations. The transmission characters of a triangular dielectric waveguide are also investigated as a special case.
