| Abstract: | The linear dispersion relation of a trapezoidally corrugated slow wave structure(TCSWS) is analyzed and presented.The size parameters of the TCSWS are chosen in such a way that they operate in the x-band frequency range.The dispersion relation is solved by utilizing the Rayleigh-Fourier method by expressing the radial function in terms of the Fourier series.A highly accurate synthetic technique is also applied to determine the complete dispersion characteristics from experimentally measured resonances(cold test).Periodic structures resonate at specific frequencies when the terminals are shorted appropriately.The dispersion characteristics obtained from numerical calculation,synthetic technique and cold test are compared,and an excellent agreement is achieved. |
