✦ Synopsis
Figure 11
Radiation pattern using an integral equation method characterizing complex geometries containing different materials, and having a sparse system to solve. The axisymmetry permits us to increase the dimensions of the studied problems, using a special formulation taking into account the Fourier mode adapted to the chosen excitation.
An efficient network representation is used, and the studied structure is entirely characterized whether it is a transmitter, receiver, or scatterer, by its scattering matrix in terms of modes of the radiating structure and spherical modes. This matrix, having small dimension, can be stored and utilized to determine interesting structure performance features like the radiation pattern, the input impedance, the antenna power gain, or the mutual coupling between several antennas.
