Controlling light is an important technological challenge—not just at the large scale of optics in microscopes and telescopes ...

Light can be sculpted into countless shapes. Yet building optical devices that can simultaneously manipulate many different ...

Tessellations aren’t just eye-catching patterns—they can be used to crack complex mathematical problems. By repeatedly ...

In an RL-based control system, the turbine (or wind farm) controller is realized as an agent that observes the state of the ...

Abstract: This paper presents a new kind of space-time-coding (STC)-enabled direction-finding approach for human target localization in smart healthcare environments. The method overcomes the ...

Modulation advances have fueled more efficient use of bandwidth, although conventional modulation formats still require allowance for upper and lower sidebands around the carrier frequency. Ultra ...
