Scattering of electromagnetic waves by impedance biconical vibrators in а free space and in a rectangular waveguide

A problem of scattering of electromagnetic waves by thin impedance biconical vibrators in a free space and in a rectangular waveguide is solved by an asymptotic averaging method and a generalized method of induced electromotive forces (EMF). An influence of the change of vibrator radius upon energy and spatial characteristics is numerically studied. Theoretical results are compared with the experimental data.
