Abstract:

A bilayer thermal cloak consists of an inner layer with very low thermal conductivity and an outer layer with higher thermal conductivity, which can eliminate the external-field distortion. However, the thermal cloak phenomenon could not be achieved for lower surrounding thermal conductivity in the bilayer thermal cloak, because the inner layer could not be completely insulated. In this paper, based on the method of machine learning, the performance of the bilayer thermal cloak has been optimized. An artificial neural network is established to intelligently learn the relation between each layer’s thermal conductivity and the cloaking performances. The optimized parameters for a better performance of the bilayer thermal cloak can be obtained, which is verified by numerical simulations. © 2025 Science Press. All rights reserved.
