Characteristics of antennas with spherical dielectric lenses



A method and efficient numerical algorithms of solving the problem of diffraction of electromagnetic waves on a multi-layer spherically symmetric structure, excited by a generalized Huygens, are considered. It is shown that the method is based on reducting the source vector problem to two scalar problems for Debye potentials. The amplifying ration and directional diagrams ...

Modeling spherical lens antennas taking into account radiator characteristics



A numerical algorithm for solving the problem of diffraction of electromagnetic waves on a multi-layer dielectric lossy sphere when amplitude-phase distribution of the exciting field is arbitrary is developed. The algorithm is based on representing the field on the source surface as an aggregate of the electrical and magnetic dipoles and reducting the vector problem to two scalar ones for the case of a point source. The results of calculating the directional diagrams and amplifying ratio are compared...
