摘要：
The method of measurement of permittivity of dielectric materials in millimeter waveband with use of a radiator with geometric-phase scanning was described. The radiator constitutes a surface-wave antenna with piecewise phase distribution of its exciting fields. The value of circuit branches of the antenna varies during the scanning. The opportunity of the solution of the inverse problem such as definition of complex permittivity with use of the global minimization method was demonstrated theoretically and experimentally. © 2008 Begell House, Inc.
