Abstract :
The problem of electromagnetic wave radiation form an arbitrarily shaped waveguide is studied. The solution process consists of two stages. At the first stage, the internal electromagnetic problem inside a waveguide is solved with the use of the R-function method and the field in the waveguide open end is determined. At the second stage, the fields in the far, intermediate, and near zones are evaluated using the Kirchoff approximation.
