SCATTERING OF THE H₁₀ MODE BY A CYLINDER WITH A LONGITUDINAL SLOT IN A RECTANGULAR WAVEGUIDE.

A rigorous solution is derived for the scattering of the H//1//0 mode by a complicated obstacle (an open cylinder) in a rectangular waveguide. The cylinder axis is parallel to the broad waveguide wall. The problem is solved by the semi-inversion method developed for an investigation of the diffraction of plane waves by a grating of cylinders with a longitudinal slit. The properties of the scattered field are studied, and new resonant effects are discovered for a rectangular waveguide loaded by a capacitive slotted cylinder.
