SCATTERING OF TE (0)SUB01 MODE ENERGY FROM A CENTERED METAL RING (WITH APPLICATION TO ANTENNA ARRAYS)

A variational expression for the fields scattered by a metal ring, centered in round waveguide, is obtained for excitation by circularly symmetric TE modes. An example is worked out and the method supported by application to a rectangular iris for which data are available. An antenna array for launching TE01 or TE02 fields in round waveguide is described, based on current rings, and measurements of its performance given. It is capable of launching rather pure fields in highly over-moded guide, but its efficiency is not high. (Author)
