Coupled leaky waveguides II: Two parallel slits in a cylinder

Theoretical expressions are derived for the effects of mutual coupling between two parallel leaky wave antennas which consists of slitted rectangular waveguides located in a cylinder. The expressions derived are presented in terms of the results for the mutual coupling of the same antennas but located in an infinite plane, with additional terms due to the curvature of the cylinder. The graphical presentation of the numerical attenuation constants for the cylindrical case are compared with those for the infinite plane.
