Abstract

In recent years, metamaterials have gradually been applied in the field of near-field radiation heat transfer sensing. Here, the near-field radiation performance of a tunable metamaterial was verified and optimized in the range of 0.5-4.0THz. The coupling effect between the LSP mode distributed on the surface of nanogradient particles and the SPP mode on the surface of the metal structure improves the near-field radiation performance of this metamaterial structure. The near-field radiation performance is determined by the gradient factor and filling factor of gradient nanoparticles. This gradient metamaterial was applied to the thermal performance sensing scheme of fabric samples. The thickness and type of fabric samples are central Asian factors affecting thermal performance. These measurement results provide a foundation for expanding the application of gradient metamaterials..
