A free-space samples material parameters validation technique

This paper describes the methodology for validating the results of measuring the electro-physical parameters (complex permittivity and permeability) of reference materials in free space. The initial data for the experiment are the samples measured by the waveguide method. The same samples were used as quasi-lenses for horn antenna for indirect analysis of phase distortions in the opening. Validation technique involves numerical experiments to obtain additional data. Then, a procedure for pairwise reconciliation of the results by event characteristics is implemented. Verification algorithm is based on IEEE standard with features difference measure comparison. The required conclusions are presented, which consist of the justification of the experiment being carried out both in the free space and the transmission line method.
