Imaging technologies are key to modern medicine and diagnosis at an early stage, potentially improving patient outcomes. Microscopic imaging allows researchers and professionals to look directly into cells, making it possible ...
Polarization, the direction in which light vibrates, provides a lot of information about the objects with which it interacts, from aerosols in the atmosphere to the magnetic field of stars. However, because this quality ...
Researchers have developed a new metasurface-based antenna that represents an important step toward making it practical to harvest energy from radio waves, such as the ones used in cell phone networks or Bluetooth connections. ...
For the first time, researchers have created a metasurface lens that uses a piezoelectric thin film to change focal length when a small voltage is applied. Because it is extremely compact and lightweight, the new lens could ...
At the interface between two media, light is partly reflected backwards into the medium from where it came and partly transmitted into the neighboring medium, like a light ray entering a sparkling pool of water. The light ...
Reconfigurable intelligent surfaces (RISs) are a type of programmable structure that can be used to control the propagation of electromagnetic waves, by changing the electric and magnetic properties of the surface. They provide ...
The phenomenon of completely eliminated backscattering in a hypothetical magnetic sphere is called the Kerker effect. It has been generalized in nanophotonics and meta-optics, and has recently been applied to such functionalities ...
Comprised of judiciously engineered microscopic photonic structures with subwavelength features, the concepts of metasurface and metamaterials have proven fruitful results in the realm of meta-optics. Previous research attentions ...
Cylindrical vector beam (CVB) multiplexing has emerged as a powerful technique to boost signal channels. Coupling and separating CVBs are two pivotal elements in CVB multiplexing communication. Although off-axis control technologies ...
Miniaturization of optical components is a challenge in photonics. Researchers of Karlsruhe Institute of Technology (KIT) and Friedrich Schiller University of Jena have now succeeded in developing a diffuser, a disk that ...
