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(More)
Transient electromagnetic fields in infinite space filled with inhomogeneous in radial direction transient medium without losses are presented by spherical modes. The initial nonstationary three-dimensional electrodynamic problem is transformed into the problem for one-dimensional evolutionary equations by means of the construction of modal basis for(More)
