This paper presents design and simulation of a switchable radiative cooler that exploits
phase transition in vanadium dioxide to turn on and off in response to temperature. The …

Metallic and dielectric nanoscatterers are optical pigments that offer rich resonating
coloration in the subwavelength regime with prolonged material consistency. Recent …

By mechanically changing the width of a nanometer gap between two optical antennas, the
coupling condition for the antennas can be seamlessly modified. This leads to a shift in the …

Phase change materials (PCMs), such as GeSbTe (GST) alloys and vanadium dioxide
(VO2), play an important role in dynamically tunable optical metadevices. However, the …

The increasing advances in thermal radiation regulators have attracted growing interest,
particularly in infrared sources, thermal management, and camouflage. Despite many …

On-chip wireless communications require optical nanoantennas with dynamically tunable
radiation patterns, which may allow for higher integration with multiple nanoantennas …

The electromagnetic response of plasmonic nanostructures is highly sensitive to their
geometric parameters. In multi-dimensional parameter space, conventional full-wave …

Wave plates based on metasurfaces have attracted intensive attention over the past decade
owing to their compactness and design flexibility. Although various wave plates have been …

We design structures with switchable, narrowband thermal absorption peaks, based on
metallic gratings incorporating phase-change materials. An insulator-to-metal phase …

We report a voltage-tunable reflective gold wire grid metasurface on vanadium dioxide thin
film, which consists of a metal-insulator-metal (MIM) structure. We excite surface plasmon …
