Abstract: A simple semi analytical method is presented.It calculates the resonance frequency in asymmetric transverse electromagnetic cell by estimating the resonance frequencies of equal inhomogeneous transmission line with open circuit and short circuit at end. The moment method was used to calculate the capacitance of crosssection, then characteristic impedance along line was obtained. The numerical results were obtained in a table by solving the combined equation of transmission line impedance transfer equation and terminal input impedance expression in gas capacitance.
