ArXiv

Analysis

This paper addresses the challenge of creating highly efficient, pattern-free thermal emitters that are nonreciprocal (emission properties depend on direction) and polarization-independent. This is important for advanced energy harvesting and thermal management technologies. The authors propose a novel approach using multilayer heterostructures of magneto-optical and magnetic Weyl semimetal materials, avoiding the limitations of existing metamaterial-based solutions. The use of Pareto optimization to tune design parameters is a key aspect for maximizing performance.
