ORG For future research related to this technique, the authors identified unresolved challenges, such as real-time processing, as well as future development directions, including improving efficiency, realizing artificial intelligence-assisted processing, reducing system size, and developing stealth-target detection....

1+ mon, 5+ day ago  (231+ words) lead image Ngo et al. have developed and tested a slot waveguide that can support ultra-high-speed communication with a simpler, more robust alignment. The group's tapered spike-free device features a slot channel formed from a subwavelength air-hole array. The resulting…...

1+ mon, 1+ week ago  (212+ words) lead image Cai et al. used the nonseparability of vectorized light to make FSO more robust to atmospheric disruption and decoding while increasing the degrees of freedom for information that can be sent. Previous attempts to mitigate atmospheric turbulence have…...

1+ mon, 2+ week ago  (60+ words) AIP. ORG The group next plans to examine how band structure engineering and junction width modulation affect carrier transport probabilities in dual-junction devices. In closing the gap between theoretical modeling and practical scenarios, the group expects to introduce novel functionalities…...

2+ mon, 1+ week ago  (155+ words) lead image "We're not just improving the material," said author Basak Bagci. "We're learning how to control its growth in a way that directly translates into better device performance." The researchers transformed their materials into working radiation sensors and evaluated…...

2+ mon, 1+ week ago  (161+ words) lead image To reduce harshness, traditional headphones typically rely on damping materials or digital equalization to suppress resonant frequencies. The problem is that conventional damping materials attenuate across the entire frequency range, rather than selectively targeting specific frequency bands. Jin…...

2+ mon, 1+ week ago  (301+ words) lead image With thousands of data centers around the world and counting, the energy required to cool servers is immense and will continue to grow. By studying the effects of parameters like airflow and server geometry, Huaitao Zhu and Jiawen…...
