Abstract

The free space method allows nondestructive dielectric characterization of materials in a wide range of frequencies and temperatures, which is basic to several applications, as the development of radomes for aerospace proposals. This paper comprises the free space method from an initial procedure, the TRL calibration, to the permittivity calculation by the NRW method, including the software implemented and its practical validation with specific materials.
