Abstract: The concept of metagratings has been proposed as an efficient method of controlling the diffraction field of electromagnetic waves. In this paper, a reflective metagrating with ...

Thomas Anderson – otherwise known as Neo – is walking up a flight of stairs when he sees a black cat shake itself and walk past a doorway. Then the moment seems to replay before his eyes. Just a touch ...

Is it possible to 3d print a diffraction pattern? Martin Lewis issues warning over using debit cards Russell Crowe details health woes as he reveals the secret behind his 26kg transformation Mona has ...

If such a simulation were possible, the simulated universe could itself give rise to life, which in turn might create its own simulation. This recursive possibility makes it seem highly unlikely that ...

I'm working with SIL Kit version 4.0.52 and would like to understand the typical sequence of API calls during co-simulation, particularly in the context of Coordinated Mode. I understand that ...

Banner patterns are items that apply a completely new design to a Minecraft banner. Some are rarer than others. To apply them to a banner, place a banner, dye and a pattern in the loom, and craft the ...

For two decades, scientists have seriously considered whether we’re living in a simulated universe. A computer scientist at the University of Louisville explores ways that humans could try to hack our ...

Optical dispersion occurs when the refractive index of a material changes with the wavelength of incoming light. This variation causes different colors to move at different speeds in transparent media ...

Ptychography is an area-by-area scanning method that uses constant, coherent illumination to scan a region of a sample in several adjacent and overlapping locations. The dispersed radiation is ...

Twisted materials—known as moiré structures—have revolutionized modern physics, emerging as today's "alchemy" by creating entirely new phases of matter through simple geometric manipulation. The term ...
