Experimental Measurement Method to Determine the Permittivity of Extra Thin Materials Using Resonant Metamaterials

Abstract

Abstract-The permittivity of extra thin silk cloth is usually measured through some complex methods in the past. Here we propose a convenient and flexible method to measure the permittivity of extra thin silk cloth using resonant metamaterial structures. The metamaterial structures used here are symmetric split ring resonators (SRRs). The principle is that the resonant frequency of the SRRs is very sensitive to the permittivity of the surrounding medium. Therefore, the relative permittivity of an extra thin medium as silk cloth can be determined. Our experimental measurement shows that the relative permittivity of the silk cloth is 4.5. A piece of printing paper is also measured with a relative permeability of 1.4. The effectiveness of the method in determining the permittivity of a solid medium is very useful in future applications.

Investigation of Quasi-Optical Bessel-Gauss Resonator at Mm- And Submm-Wavelengths

“…Finally, we compare the resonating modes between QOBR and QOBGR at SubMM-wavelengths. The Bessel-Gauss beam generated from the designed QOBGR have many promising applications in the MM-and SubMM-wavelength range, such as power transfer [26], millimeter wave imaging [27][28][29] and medium parameter measurement [30]. These applications are being studied at present.…”

“…For such materials, the use of resonant circuits is an interesting alternative [6]. Indeed, in this case, the impact of the impedance variation on the resonant frequency is more significant than the impedance variation itself.…”
