Power waves and scattering parameters in magneto-inductive systems

AIP Advances, 2021
Difficulties arise in the definition of power flow in transmission-line systems with a complex propagation constant. These were resolved by Kurokawa using quantities known as “power waves,” which contain both voltage and current terms and correctly ...

Sinking Organic Particles in the Ocean—Flux Estimates From in situ Optical Devices

Frontiers in Marine Science, 2020
Optical particle measurements are emerging as an important technique for understanding the ocean carbon cycle, including contributions to estimates of their downward flux, which sequesters carbon dioxide (CO2) in the deep sea.

A chip-integrated coherent photonic-phononic memory

Nature Communications, 2017
Optical storage implementations based on optomechanical resonator are limited to one wavelength. Here, exploiting stimulated Brillouin scattering, the authors demonstrate a coherent optical memory based on a planar integrated waveguide, which can operate

Boosting Cu(In,Ga)Se2 Thin Film Growth in Low-Temperature Rapid-Deposition Processes: An Improved Design for the Single-Heating Knudsen Effusion Cell

Engineering, 2021
The Knudsen effusion cell is often used to grow high-quality Cu(In,Ga)Se2 (CIGS) thin film in co-evaporation processes. However, the traditional single-heating Knudsen effusion cell cannot deliver complete metal selenides during the whole deposition ...
