| Abstract: | The general electromagnetic fields of the transverse magnetic mode(TM) in a sectoral waveguide are derived from the wave equation and the appropriate boundary conditions on the walls by using the separation variable method. The cutoff wave numbers of the TM modes in a waveguide with the various subtended angles and the ratio between the outer and inner radii are computed and tabulated. then the cutoff wavelength expressions, exact and approximately formulas are given. |
