In this paper, a method to generate dual asymmetric non-diffracting beams by a transmission metasurface is introduced. A metasurface is regularly divided into two independent complementary sub-arrays.

A retired researcher has detected an unusual pulse in the light of nearby stars while looking for signs of extraterrestrial intelligence. Aliens are one possible explanation for the strange signal ...

Menon and co-authors patterned 20,000 diffracting rings on a glass wafer in a way that allows a range of wavelengths to be magnified together. The rings have separations smaller than the ...

“There’s a benefit to being able to mechanically move the diffracting elements in order to enhance imaging,” Professor Cohen said. The robot itself can be used as a diffraction grading, or a ...

Multiple bullets containing a tiny spectrometer could be shot into the lunar soil by an astronaut or rover, allowing analysis of a wide area all at once.

The non-diffracting nature of the beam overcomes optical scattering effects that have previously hindered precise energy deposition, inducing extremely small, localized voids inside the wafer.

The non-diffracting nature of this special laser beam, which is created with advanced holographic projection techniques, enables precise energy localization. This, in turn, leads to high temperature ...

ABSTRACT: The detection of DNA as the transforming principle in bacteria 95 years ago, almost immediately led to 1) refutation of the old and heavily disputed concept of inheritance of acquired ...

We show that a transverse field zero is always accompanied by non-diffracting polarization structures, whose geometries are independent of the distance to the source, including an enclosing intensity ...
