The characteristics of the radiation field of the monopoles on perfectly conducting spherical scatterer — spherical antennas are discussed in the paper. To solve this problem the authors used the solution for the radiation field of a single monopole excited at the point of contact with the sphere. Monopoles are located in the equatorial plane and driven the individual voltage sources. The dependences...
The problem of electromagnetic waves radiation by a longitudinal slot in the broad wall of a rectangular waveguide is solved. The slot is radiating into half space above a perfectly conducting plane in the presence of two passive vibrators (monopoles) having variable distributed surface impedance in the space above the plane.
The 3D vector problem of diffraction of the field of a thin impedance vibrator located over an ideally conducting infinitely thin rectangular screen is solved. The vibrator may have surface impedance distributed over its length. Asymptotic expressions for the current on a horizontal impedance vibrator placed over an infinite plane, obtained by averaging method were used. Full radiation fields in all...
