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 ...

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

Simultaneous multi-signal quantification for highly precise serodiagnosis utilizing a rationally constructed platform

Nature Communications, 2019
Single channel detection methods often suffer from false positives when analysing biological samples. Here, the authors report on the development of a three-channel detection device for measuring hydrogen sulphide in serum and demonstrate application in ...

Polarization-Maintaining Single-Frequency Fiber Laser With Quadruple Wavelengths at the C-Band

IEEE Photonics Journal, 2018
In this paper, a polarization-maintaining quad-wavelength (QW) single-frequency fiber laser (SFFL) at the C-band with the novel and compact structure is demonstrated. Applying the rate equations and multiple coupled nonlinear Schrödinger equations,

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 ...

Broadband Transformation Optics Devices [PDF]

Materials, 2010
Recently we have suggested that two-dimensional broadband transformation optics devices based on metamaterial designs may be built using tapered waveguides. Here we review application of this principle to broadband electromagnetic cloaking, trapped rainbow, and novel microscopy devices.

Divalent europium-doped near-infrared-emitting phosphor for light-emitting diodes

Nature Communications, 2019
Here the authors report a near-infrared K3LuSi2O7:Eu2+ phosphor for non-visible light source application. The selective site occupation of Eu2+ in LuO6 and K2O6 polyhedrons is found to be responsible for the light emission and these insights could serve ...
