This paper presents a complex permittivity measurement method for low-dispersive materials as a function of frequency. The introduced method relies only on transmitted power signals which are collected using a spectrum analyzer/power meter, removing the need for phase measurements and a vector network analyzer. This method provides a very good accu...

... section briefly discusses our power method applied to a coaxial line structure. The method can be also applied to other permittivity reconstruction setups such as the freespace one. Fig. 1 shows a coaxial line connected to a signal generator with an internal source resistance of R s and to a spectrum analyzer with a load resistance of R L . Solving Maxwell equations for the transmitted power delivered to the spectrum analyzer analytically results ...
