✦ Synopsis

A new technique, generalized differential quadrature ( ) GDQ , is applied to determine the propagation characteristics of hollow metallic wa¨eguides of square, rectangular, circular, and elliptical cross sections. The results show excellent agreement with theoretical ¨alues.

( ) The GDQ is compared with surface integral formulation SIF and the ( ) conjugate-gradient method CGM , and is shown to ha¨e high accuracy, speed, simplicity, and efficiency.
