A new free-space technique for measuring the complex permittivity and thickness of materials
1999•IET
A novel free-space method for the measurement of complex permittivity and thickness of
materials has been developed. Antenna-medium coupling is taken into account. Thus, the
antenna can be placed in close proximity to the sample material. Compared with
conventional free-space techniques, the proposed method achieves a higher accuracy and
it can be used in the UHF frequency range. An example is provided to demonstrate the
performance of the method using simulated data.
