Diffusion and wave propagation are both fundamental transport mechanisms, but they have
intrinsically different dynamics, governing equations, and applications. Over the past …

Diffusion driven by temperature or concentration gradients is a fundamental mechanism of
energy and mass transport that inherently differs from wave propagation in both physical …

Metamaterials facilitate on-demand manipulations of mass diffusion and have been broadly
employed in many fields covering optics, electronics, and particle dynamics. However, the …

Intelligent metamaterials have aroused intensive research interest due to their adaptive
responses to environmental changes. However, existing transformation-thermotics-based …

The concentrating efficiency of a thermal concentrator can be reflected in the ratio of its
interior to exterior temperature gradients, which, however, has an upper limit in existing …

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 …

Janus metamaterials, metasurfaces, and monolayers have received intensive attention in
nanophotonics and 2D materials. Their core concept is to introduce asymmetry along the …

The classical effective medium theory (EMT) provides a powerful tool in designing
heterogeneous-composite functional thermal metadevices. But it is usually appropriate for …

Remote temperature control can be obtained by a long‐focus thermal lens that can focus
heat fluxes into a spot far from the back surface of the lens and create a virtual thermal …

Controlling heat transfer with artificial functional materials has been a promising route
towards the efficient and smart utilization of thermal energy in modern society. At the …
