✦ Synopsis

A wa¨eguide structure consisting of a wedge-shaped dielectric region bounded by two conducting planes is introduced. An exact analytical solution of this wa¨eguide is presented. Propagation properties of the wa¨eguide, including modal fields, dispersion characteristics, cutoff conditions, and dielectric and conductor losses, are deri¨ed for all guided modes and are examined numerically for se¨eral lower order modes. This wa¨eguide supports only TE and hybrid modes, but not TM modes. Compared to hollow metal wa¨eguides, the wedge-shaped wa¨eguide can pro¨ide a wider single-mode frequency range, allowing more information to be transmitted.

## Abstract A fast technique is proposed to determine the complex propagation constants of the leaky and Berenger modes of circular dielectric waveguides terminated by a perfectly matched layer (PML). The method relies on a coordinate transformation in the complex plane and uses the approximate ana
