Design and Measurement of an All-Dielectric Metamaterial with Large Spectrum Smooth Transmission and Applications for Measuring the Thermal Conductivity Properties of Jade Carving Materials
摘要
An all-dielectric metamaterial sensing scheme is proposed and applied in order to measure the thermal conductivity of jade carving materials with smooth spectral lines in a band. In the range of 6-40 THz, the transmission spectrum lines of jade carving materials are smooth and stable. The thermal conductivity of jade carving material decreases with the increase in thickness, while the thermal resistance increases gradually. The measurement results of four kinds of jade carving materials show that the composition of materials is an important factor affecting the heat conduction property. These measurement results provide a basis for expanding the application of metamaterial sensors.
