Classical physics theories suggest that when two or more electromagnetic waves interfere destructively (i.e., with their electric fields canceling each other out), they cannot interact with matter. In ...
Scientists in Japan have managed to manipulate light as though it was being influenced by gravity. By carefully distorting a photonic crystal, the team was able to invoke “pseudogravity” to bend a ...
Ultrathin structures that can bend, focus, or filter light, metasurfaces are reshaping how scientists think about optics. These engineered materials offer precise control over lights behavior, but ...
Fig. 1 (a) Schematic of a PM that consists of two nanobeam cavities. (b) Normalized profile of the electric field (Ex at left and Ey at right) for the S and AS mode Polarization is an intrinsic ...
"It's a sheer physical challenge to construct sieves with such precision." When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. To truly understand ...
A tunable FEL generates narrowband terahertz radiation, which is focused onto the s-SNOM tip and is backscattered into a photoconducting detector. Inset: terahertz light scatters off the edge of a ...
The ability to see invisible structures in the human body, such as the inner workings of cells, or the aggregation of proteins, depends on the quality of the microscope employed. Ever since the first ...
Power functional theory is a new approach that makes it possible to describe precisely the dynamics of many-particle systems over time. Physicists at the University of Bayreuth are among the ...
Experts involved in all aspects of photonics and optics are set to meet at the 16th edition of Optatec, the trade fair for optical technologies, components and systems, which will be held between May ...
This engineering exam, which is a gateway to some of the premium engineering colleges such as IITs, NITs and more, cover ...
