Frequency behavior of Raman coupling coefficient in glasses

open access: yes, 2002
Low-frequency Raman coupling coefficient of 11 different glasses is evaluated. It is found that the coupling coefficient demonstrates a universal linear frequency behavior near the boson peak maximum and a superlinear behavior at very low frequencies ...

Research on four-coil structure of magnetically coupled resonant wireless power transmission system

open access: yesGong-kuang zidonghua, 2019
For the position of four coils of traditional four-coil magnetically coupled resonant wireless power transmission system is relatively fixed and cannot be changed at will, which leads to limitation of its use, a new four-coil structure was proposed ...
