ANALYSIS OF NEAR TO FAR FIELD TRANSFORMATION BASED ON RAOWILTON-GL1SSON (RWG) BASIS FUNCTION USING SURFACE EQUIVALENCE THEOREM

摘要

The RWG basis function is applied for the transformation of near to far field of two dimensional triangular grid. Here the surface equivalence theorem is applied and the equivalent current density, J_z in the TMz case or Mz in the TEz case, on the radiation contour is interpolated. The interpolation is valid for the near to far field transformation in frequency domain. Numerical results in this domain is verified by comparison with analytical solution.
