Analysis of open-type dielectric waveguides by the finite-element iterative method
Abstract
Dispersion characteristics for open-type 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.
