Schematic of chiral terahertz generation and control: A femtosecond laser interacts with a patterned spintronic emitter, producing elliptically or circularly polarized terahertz waves. Rotating the ...
Based on a suitable band structure, the synergistic effect of oxygen vacancy defects and an electromagnetic field facilitates electron transfer. This process thereby achieves broadband absorption ...
Gravitational waves from inflation generate a faint but distinctive twisting pattern in the polarization of the cosmic microwave background, known as a "curl" or B-mode pattern. For the density ...
When the Harvard-Smithsonian Center for Astrophysics announced a press conference for a "Major Discovery" (capital letters in the original e-mail) involving an unspecified experiment, rumors began to ...
The simulated normalized 3D scattering patterns of (a) 0°-, (b) 45°-, (c) 90°-polarized reflection at 3.5 GHz. 2D STPC matrices and measured normalized far-field scattering patterns. USA, September 2, ...
