Building Material Characterization from Complex Transmissivity Measurements at 5.8 GHz

Iñigo Cuiñas and Manuel García Sánchez

Page 1269.

Abstract:

In this letter, an improvement of the well-known internal multireflection model of transmission coefficients is proposed in order to obtain better agreement with complex measured data. The reason for the introduced changes is explained. To obtain the data, measurements were performed at 5.8 GHz using a vector network analyzer, which provided information on the amplitude and phase of the transmission coefficient. By comparing the model and measurements, both the real and imaginary parts of the material complex permittivity were estimated for four different building materials.
