ABSTRACT

This paper presents a comparison of measurement results of polytetrafluoroethylene (PTFE) is loaded waveguide between Nicolson-Ross-Weir (NRW) method and FiniteElement Method (FEM).The permittivity of PTFE values obtain from optimization technique and errors analysis have been conducted for scattering parameters incalculation and simulation results, variation mean relative errors with thickness of sample have been found and plotted.
