Antennas receive and transmit electromagnetic waves, delivering information to our radios, televisions, cellphones and more.

Researchers have developed a novel metasurface-based method to generate terahertz complex vector light fields using surface ...

New metasurfaces with nanoantennas could replace lenses and enhance AR, VR, LiDAR, and more by precisely controlling light.

Quantum information scientists at the Department of Energy’s Oak Ridge National Laboratory successfully demonstrated a device that combines key quantum photonic capabilities on a single chip for the ...

Abstract: It is demonstrated that the polarization of light which has been diffracted from shear ultrasonic waves is not, in general, perpendicular to that of the incident lights but depends on the ...

Figure 1: Schematic diagram of the metasurface device. With the rapid development of information and communication technologies, especially in the context of 5G, 6G networks, artificial ...

Consequently, the whole apparatus of impedance may be neatly adapted for representation of elliptical polarization. In Part II G. A. Deschamps recalls and applies a method of H. Poincaré for ...

South Korean President Yoon's recent declaration of martial law highlights the nation's political disfunction. Dr. Yul Sohn ...

When the incident wave is an on-chip surface wave, the mode "surviving" in free space is a specific circularly polarized light, and both the radiation angle and polarization state of this mode can be ...
