Fields and Waves in Elliptic Waveguides
Abstract
In order to calculate cut-off wavelengths of elliptic waveguides without trying to solve the roots of Mathieu functions, a first order approximation is derived. The elliptic waveguide is decomposed in two circular waveguides for even and odd mode propagation. The cut-off wavelengths of these waveguides are calculated and used as approximate cut-off wavelengths of the elliptic waveguide. Cut-off wavelengths for the dominant TE11-mode can be approximated with a maximum error of 5 percent for all eccentricities. The approximation is also valid for the other modes for small eccentricities. Wave guides, Elliptic waveguides, Wave lengths in transmission lines, Analysis of waves.
