Antennas receive and transmit electromagnetic waves, delivering information to our radios, televisions, cellphones and more.

Researchers have developed a novel metasurface-based method to generate terahertz complex vector light fields using surface ...

This approach utilizes a detailed modeling of the optical system to derive physically realizable Mueller matrices, which helps in accurately correcting for polarization crosstalk. This method is ...

This study details the implementation of a wavelength-tunable ultra-stable optical frequency comb (OFC), which is generated by a passively mode-locked all-polarization-maintaining Erbium (Er)-doped ...

Abstract: The self-coherent scheme is attractive for free space optical communications (FSO) due to the higher oscillator-signal mixing efficiency compared to a coherent scheme. In this paper, the ...

Materials scientists have long been exploring advanced materials for environmental and energy applications, with ...

Abstract: Both the coupled-wave equations (CWEs) and coupled-power equations (CPEs) derived from coupled-mode theory (CMT) are presented, along with their analytical solutions, to describe the ...

Using the nanostructures found on butterfly wings, scientists have developed a simple and inexpensive way to analyze ...

Tungsten disulfide nanotubes (WS2-NTs), first discovered in 1992, have long captured the attention of researchers for their ...

Even as a lifelong skier and professional gear snob, I still sometimes find the search for perfect ski gear ...
