Definitions

  • the specific configuration of the system of the present invention which produces the effect of reducing undesired currents, is based on the implementation of chokes with variable dimensions in keeping with each problem, on the metal surfaces considered to be critical.
  • one of the embodiments of the invention focuses on disposing corrugations on metallic planes with a canonical wave solution and where Kildal's correction can be applied. This analysis can also be used in the reduction of surface waves of electric fields since these are supported on magnetic surfaces.
