摘要

本文设计并制造了一种基于梯度折射率超材料的电磁黑洞，通过在容易获得的材料上钻孔来实现多模腔的高效微波加热。当相对介电常数实部在10 ~ 80范围内，被加热材料的损耗正切在0.1-1范围内变化时，该黑洞在提高微波能量利用率方面表现出优异的性能。以不同体积分数的乙醇水溶液为实验材料，验证了电磁黑洞的有效性，实验结果与仿真结果吻合较好。

Electromagnetic Black Hole for Efficiency Microwave Heating Based on Gradient-Index Metamaterials in Multimode Cavities

In this work, an electromagnetic black hole based on gradient-index metamaterials is designed and fabricated by drilling holes in easily available materials to achieve efficient microwave heating in multimode cavities. This black hole shows superior performance in improving the utilization of microwave energy when the real part of the relative permittivity varies from 10 to 80 and the loss tangent of the heated material changes within 0.1–1. Different volume fractions of ethanol aqueous solution are used as test material to verify the effectiveness of electromagnetic black hole, and the experimental results are in good agreement with the simulation results.

期刊介绍： The IEEE Microwave and Wireless Components Letters (MWCL) publishes four-page papers (3 pages of text + up to 1 page of references) that focus on microwave theory, techniques and applications as they relate to components, devices, circuits, biological effects, and systems involving the generation, modulation, demodulation, control, transmission, and detection of microwave signals. This includes scientific, technical, medical and industrial activities. Microwave theory and techniques relates to electromagnetic waves in the frequency range of a few MHz and a THz; other spectral regions and wave types are included within the scope of the MWCL whenever basic microwave theory and techniques can yield useful results. Generally, this occurs in the theory of wave propagation in structures with dimensions comparable to a wavelength, and in the related techniques for analysis and design.
