| Abstract: | A research on the cutoff-wavelength and field-construction of higher order modes in square coaxial lines is carried on with concrete analyses of different boundary conditions by FDM method. Taking TE10 as an example, we have got cutoff-wavelengths and electric potentials by FDM method and MATLAB. |
