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 ...

A new publication from Opto-Electronic Advances; DOI 10.29026/oea.2026.250149, discusses a quarter-wave geometric-phase ...

A new publication from Opto-Electronic Advances; DOI 10.29026/oes.2022.210014 overviews terahertz metasurface zone plates with arbitrary polarizations to a fixed polarization conversion. As an ...

So I've been familiar with the basics of polarization since forever, but I recently realized circular polarization is a mystery to me. I've heard of it in conjunction with eg satellite broadcasts, but ...

Holographic images: the two figures on the left are two holographic images produced by a leaky-wave metasurface at two different distances from the device surface. The other figures are distinct ...

In this article you will get the clue that from where and how the questions are being framed from chapter Wave Optics a) Described briefly, with help of a necessary diagram, the polarization of light ...

Terahertz (THz) waves, which are located between microwaves and infrared light in the electromagnetic spectrum, can pass through many materials without causing damage, making them useful for security ...
