Abstract :
This contribution presents an analytical method for the calculation of resonances of higher order modes 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 TEM waveguides with either rectangular or circular cross section.
