Abstract

An all-dielectric metamaterial is proposed and applied in measurement of the thermal conductivity of jade carving materials. This metamaterial achieves a smooth transmission spectral over a large frequency range, which is different with traditional electromagnetic (EM) metamaterial/metasurface sensors. In the 2-36THz band, the average transmittance and reflectance are: 0.716 and 0.155, and the change in transmittance is relatively small and stable, which is suitable for measuring the transmission spectrum of jade carving samples. The thermal properties of the jade carving sample are weakened with the thickness increasing (from 1mm to 1.6mm), and the sensing sensitivities are: 1.8A/mm, 2.8A/mm, and 2.7A/mm. The heat conduction properties of the four jade carving materials (Jadeite, Turquoise, Color Jade, and Yellow stone) are measured by applying this metamaterial. The measured thermal diffusion coefficients are: 3.41, 2.72 , 4.65, and 3.75. And the measured thermal resistance coefficients are:15.38, 12.32, 20.79, and 16.64. This metamaterial is suitable for measuring the thermal conduction properties of jade carving materials..
