Here we show that multimode quasistatic cavity resonance can provide room-scale wireless power transfer. The approach uses multidirectional, widely distributed currents on conductive surfaces that are placed around the target volume. It generates multiple, mutually unique, three-dimensional magnetic field...
A multi-mode resonator includes: a housing having a cavity therein; and a plurality of resonance ribs which are arranged radially around a center of the cavity with a predetermined interval therebetween. Each of the plurality of resonance ribs includes a body having a lower end and an upper ...
In the field of nanomechanics, parametric excitations are of interest since they can greatly enhance sensing capabilities and eliminate cross-talk. Above a certain threshold of the parametric pump, the mechanical resonator can be brought into parametric
此外,双模式 AFM 中的调幅-调频模式(AM-FM mode)可以用来研究样品的黏弹性等性质,利用两个 不同频率的激励信号来激励微悬臂振动,其中低频 的振动信号采用振幅调制模式来得到样品形貌, 而高频的振动信号采用频率调制模式来获得共振频率 和振幅,分别反映了样品的硬度(弹性)和能量耗散 (黏性)。
5b, when the self-resonance frequency equals the WPT resonance frequency, the Tx (Rx) will resonant in the different phases. Full size image Multimode of the proposed metasurface The proposed metasurface has three modes: the lower mode, the higher mode, and the balanced mode. Since we ...
Bottom skip quasi-resonance mode means that power MOSFET is just switched on at the only 2nd timing of the lowest voltage of V_(DS), after skipping over the 1st switching on timing of the lowest ringing oscillation voltage generated by quasi resonance, during every switching cycle. This IC ...
The magnetophonon resonance in a multimode crystal of the solid solution Zn x Cd y Hg 1 x y Te ( x =0.08, y =0.11) was investigated in the temperature interval from 77 to 200 K. To interpret the obtained structure of the magnetophonon resonance spectrum, the phonon modes of three com...
The composition and chemical structure are confirmed by the nuclear magnetic resonance (NMR, NMR-400M (AVANCE III 400 M), SUSTech Core Research Facilities), and the 1H NMR (D2O, 400 MHz) spectra are: 8.75 (s, 1H), 7.49 (d, J = 19.1 Hz, 2H), 6.47 (d, J = 17...
