Abstract

The concept of the electromagnetic energy harvesting by thermoelectric system based on a broadband metal-insulator-metal-based metamaterial combined with a magnetic tunnel heterostructure, exhibiting the tunnel magneto-Seebeck effect, is presented. Based on finite-element calculations, the optimal design of such a broadband metamaterial with conductive TiN layer was selected to ensure maximum adsorption of radiation in a given wavelength range (solar spectrum/microwave region). The microwave heating of the magnetic tunnel heterostructure after passing the electromagnetic wave through the metamaterial and corresponding thermo-voltage response were also evaluated, indicating the possibility of using such system for an effective energy supply of low-power electronic devices.

具有隧道磁塞贝克效应的磁隧道结与宽带超材料吸收器组合结构中电磁能量收集的前景

提出了基于宽带金属-绝缘体-金属基超材料结合具有隧道磁塞贝克效应的磁隧道异质结构的热电系统电磁能量收集的概念。基于有限元计算，选择了具有导电TiN层的宽带超材料的优化设计，以确保在给定波长范围内(太阳光谱/微波区)最大限度地吸附辐射。同时，对磁隧道异质结构在电磁波通过超材料后的微波加热和相应的热电压响应进行了评价，表明了利用该系统作为低功率电子器件的有效能量供应的可能性。
