Researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have created a chip-scale device that can dynamically control the "handedness" of light as it passes ...

Schematic illustration of MEMS-integrated twisted bilayer photonic crystals illuminated by right-handed circularly polarized and left-handed circularly polarized beams. Harvard engineers have built a ...

How to read Bode plots to assess dynamic control behavior of a power-supply design. Observing Bode plots from an example voltage regulator to observe control-loop speed and stability. This article ...

With the eOC (electronic open circuit) hydraulic architecture, machine manufacturers can take full advantage of their mobile machines. The Rexroth eOC portfolio includes software and hydraulic ...

Engineers created a MEMS-tunable twisted bilayer photonic crystal chip that dynamically adjusts twist angle and spacing to control light chirality and distinguish circular polarization. (Nanowerk News ...
