Mathematical models of spheroidal spiral-frame radiating structures

The article considers mathematical models of two spheroidal spiral-frame emitters, built on the basis a general approach involving use an integral representation electromagnetic field. internal problem electrodynamics is reduced to system Fredholm equations 1st kind. resulting was solved by method moments with piecewise constant functions and delta as test functions. In this case, local linearization generating conductors structures under consideration carried out. dependences current distributions, input resistance, radiation characteristics frequency have been studied. It shown that standing, traveling, mixed waves can exist in consideration. regime determined wave sizes geometry determines behavior resistance range. Despite similar geometry, considered certain differences.
