Analysis of Open-Type Dielectric Waveguides by the Finite-Element Iterative Method

Dispersion characteristics for open-typed dielectric waveguide structures operated at millimeter-and submillimeter-wave frequencies are calculated by a finite-element iterative procedure with a given criterion on the maximum field strength at the virtual boundary. Numerical results for a rectangular...

Zusammenfassung:	Dispersion characteristics for open-typed dielectric waveguide structures operated at millimeter-and submillimeter-wave frequencies are calculated by a finite-element iterative procedure with a given criterion on the maximum field strength at the virtual boundary. Numerical results for a rectangular dielectric image guide are presented and compared with results from other methods. The strip dielectric guide and the insulated image guide with finite- or infinite-width substrates are also analyzed.
