Researchers at Penn State have developed a metamaterial coating that allows coated objects to function normally while appearing as something other than what they really are. The 'illusion coatings' work by using copper patterns designed to create the desired result, enabling practical applications for cloaking metal antennas and sensors.
The project aims to create rapidly configurable metasurfaces that can be tuned in real-time, enabling the development of advanced optical technologies and quantum information devices. The research team will combine nanophotonics with quantum photonics to achieve unprecedented control over photon emission.
Researchers at UT Austin propose a battery-powered active cloak that draws energy from a battery, allowing objects to become undetectable to radio sensors over a greater range of frequencies. This technology has applications in improving cellular and radio communications, biomedical sensing, and near-field imaging.
Researchers at Purdue University have developed a new hologram technology using tiny nanoantennas that can control light with unprecedented efficiency. The metasurface, thousands of V-shaped nanoantennas, enables the creation of ultra-efficient devices for sensing, displays and information processing.
Researchers have developed metasurfaces that can manipulate and control light, enabling new optical technologies with applications in solar cells, computers, and telecommunications. The technology uses metamaterials to harness surface plasmons and reduce the size of photons, promising breakthroughs in nanophotonic devices.
Researchers at NIST have demonstrated a unique fluid-tuned 'metasurface,' which can concentrate energy in a material and change its properties. The metasurface's resonant frequency can be tuned by adding purified water, allowing it to reflect, store, or transmit energy.
