โœฆ Synopsis


Elliptical waveguides and irises are i m p o ~a n t for application in wideband filters and aduanced dual-mode filters. In this Letter we present a general formulation for the multimode equivalent network representation of planar waveguide junctions involving elliptical waveguides. The modes of the elliptical waueguide are obtained by transforming the Helmholtz equation in elliptical coordinates into an equiualent linear matrix eigen-

value equation so that the use of Mathieu functions is avoided. Finally, numerical and experimental results for a number of junctions are presented, and good agreement is found.
