Abstract :
Energy transformation of a transient TEM-wave in a coaxial waveguide into energy of reflected and radiated waves on a coaxial aperture is investigated. The radiation problem is solved by means of the modal basis method in the time domain. The analytical expressions for amplitudes of fields radiated into free space and reflected inside the waveguide are obtained for step-wise time dependence of amplitude. of exciting TEM-wave. Time dependencies of instant power of the electromagnetic waves in waveguide and free space are obtained. The analysis of the influence of the problem geometry and exciting signal parameters on effectiveness of radiation is carried out.
