Resonances in Tapered Double-Port TEM Waveguides
Veröffentlicht in 2008
In this paper resonances in tapered double-port TEM waveguides are used as benchmark for simulations. FEM simulations with COMSOL Multiphysics® and simulations using generalised telegraphist's equations with MATLAB® are compared to ananalytical method capable of calculating the resonances of higher order modes. It is valid for tapered double-port TEM waveguides with constant characteristic impedance. Because these resonances determine the usable bandwidth of the waveguide their precise knowledge is essential. The accuracy of the proposed method has been proven using a TEM waveguides with circular cross section.
