Abstract

The application of the coupled‐mode method (CMM) for calculating the propagation constants and the electromagnetic‐field distribution in chirowaveguides is well known. In this paper, two different formulations of the method are revised and compared, and are then extended to partially filled parallel‐plate waveguides. © 2004 Wiley Periodicals, Inc.

## Abstract The main drawback of the coupled‐mode method is the poor convergence and accuracy of the discontinuous field components. The greater the discontinuity, the worse these problems become. This Letter presents an improvement of the method, allowing this drawback to be minimized. © 2002 Wile
