Özet
A time-domain free-space technique has been proposed to extract relative permittivity (epsilon(r)) and effective conductivity (sigma(e)) of low-loss dielectric samples using their metal- and air-backed calibration-free reflected powers. Numerical computations and 3-D electromagnetic simulations were performed to validate the method. A sensitivity analysis was carried out to examine its accuracy. Calibration-free time-domain free-space measurements over 1-12 GHz were conducted by VNA to extract epsilon(r) and sigma(e) of polyethylene and polypropylene low-loss samples.
