The energy and resonant properties of a longitudinal slot in a waveguide partially filled with dielectric

The paper considers a narrow longitudinal slot in the wide wall of a rectangular waveguide with a layer of dielectric arranged parallel to the waveguide narrow walls. The resonant properties of the slot and the behavior of its scattering matrix elements are investigated depending on physical dimensions and ε of the dielectric

The impact of position of a magnetic dipole with respect to the outer boundary of an open cylindrical volume on the remote zone field

A solution is obtained to the strictly formulated problem concerning radiation of a magnetic dipole located on the outer surface of an ideally conducting circular cylinder with an infinite longitudinal slot. It is shown that the dipole position with respect to the edge of a conductive cylindrical surface may substantially affect the radiation field distribution in the remote zone
