We study a transmission problem of an electromagnetic pulse with given transversal structure passing through a waveguide converter from TM01 to TE11 mode of circular waveguide. Using FDTD numerical simulation method we have investigated mode structure of the pulse at the output of the converter and its dependence on pulse length at the input. Also we have obtained frequency characteristic by calculating Fourier response for a pulse with wide spectrum.
