Diffusion Metamaterials: Basic Simulation Methods

Recent theoretical advances have spurred the development of metamaterials endowed with exceptional thermal properties. Traditional approaches, however, falter when applied to irregular geometries. The application of coordinate transformation theory necessitates metamaterials that exhibit inhomogeneous and anisotropic properties, a demand that natural materials struggle to meet. Fortunately, cutting-edge simulation techniques are poised to bridge this gap, enabling the use of bulk materials. This chapter delves into the most prominent simulation strategies that harness intelligent algorithms for the creation of metamaterials, and evaluates their efficacy through finite element analysis. These algorithm-driven designs promise to significantly broaden the adaptability, functionality, and flexibility of metamaterials beyond the constraints of conventional configurations.
