Because of analogies between the 2D Maxwell equations and water wave equations,
methods for manipulating electromagnetic waves based on photonic crystals and …

The advancement in electromagnetic metamaterials, which commenced three decades ago,
experienced a rapid transformation into acoustic and elastic systems in the forms of …

Classical thermodynamics often helps to passively describe macroscopic heat phenomena
of natural systems, which means people almost cannot change the heat phenomena, but …

We combine theory and experiment to demonstrate that a carefully designed gradient meta-
surface supports high-efficiency anomalous reflections for near-infrared light following the …

Metasurfaces, two‐dimensional versions of metamaterials, retain the great capabilities of
three‐dimensional counterparts in manipulating electromagnetic wave behaviors, while …

Utilizing a multilayered composite approach, we have designed and constructed a new
class of artificial materials for thermal conduction. We show that an engineered material can …

Underpinned by the advent of metamaterials, transformation optics offers great versatility for
controlling electromagnetic waves to create materials with specially designed properties …

Luneburg lenses have superior performance compared with conventional lenses made of
uniform materials with specially designed surfaces, but they are restricted by the difficulty of …

The field of transformation optics shows that media containing gradients in optical properties
are equivalent to curved geometries of spacetime for the propagation of light. Conformal …

By introducing concepts from transformation optics to the manipulation of water waves, we
design and experimentally demonstrate two annular devices for concentrating waves, which …
