Abstract

The problem of the excitation of a rectangular waveguide by a transient current is solved in the time domain by the evolutionary equation technique and the Riemann function method. The field radiated from the open end of a rectangular waveguide is calculated in the Kirchhoff approximation using the vector potential method. The dependences of the amplitude of the radiated field on time and angle are investigated and compared with numerical results.
