Calibration-free time-domain free-space permittivity extraction technique
IEEE Transactions on Antennas and Propagation, 2021•ieeexplore.ieee.org
A time-domain free-space technique has been proposed to extract relative permittivity () and
effective conductivity () 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 and of polyethylene and polypropylene low-loss …
