A Thermal–EM Concentrator for Enhancing EM Signals and Focusing Heat Fluxes Simultaneously

Abstract: The simultaneous concentration of electromagnetic (EM) waves and heat fluxes in the same target region within an on‐chip system has substantial academic research importance and practical application value. However, the existing research is primarily aimed at the design and experimentation of concentrators for individual EM waves or temperature fields. In this study, a thermal‐EM concentrator capable of simultaneously concentrating EM waves and heat fluxes is designed using transformation optics and thermodynamics and fabricated using engineered thermal‐EM metamaterials. Both the numerically simulated and experimentally measured results demonstrate the concentrating capability of the proposed thermal‐EM concentrator, which can concentrate broadband transverse magnetic (TM)‐polarized EM waves ranging from 8 to 12 GHz and heat flux to the same target region within an on‐chip operating environment. The proposed thermal‐EM concentrator can be utilized for the efficient cooling of the specified component and for simultaneously enhancing the radiation and reception efficiency of the EM antenna within an on‐chip system.
