About excitation of round waveguide by a point current source
Abstract
The problem of tensor Green function formulation for electric vector potential G(sub e)(r-vector,r'-vector) is solved as a problem of tensor spheric wave diffraction on inner surface of a round waveguide. It is shown that G(sub e)(r-vector,r'-vector) is a superposition of tensor Green-function of free space and a regular Green function of round waveguide G(sub e)(sup (0))(r-vector,r'-vector) being a solution of homogeneous Helmholz equation which satisfy unhomogeneous boundary conditions on waveguide surface. The obtained results may be applied in design of UHF installations and accelerating technique in which charged round waveguides are used.
