| Abstract: | The general electromagnetic fields and the approximate formulas of the transverse elec-trie mode in a sectoral waveguide are found,and the approximately simplified formulas of the dominant mode from the general relationships are discussed. The strict and approximate calculation of the cutoff wavelength for the dominant mode is given. The scalar Helmholtz equation in cylindrical coordinate is constructed, using the method of separating variable, and fourier transform,and residue theory,and the Green's function and field of the transverse electric mode associated with the electric diple are also obtained. |
