Magnetic resonance coupling (MRC) has been utilized in wireless power transfer (WPT) to achieve mid-range contactless supply. However, unintended users might also draw from the transmission devices. In this letter, an MRC-WPT system with multiple transmitters, one intended receiver, and receiver is investigated. We formulate a security problem by limiting receiving and, at same time, maximizing of user. Such optimization general nonconvex. Nevertheless, global optimal solution can be...
The acoustic emission characteristics of rock specimens under different initial unloading confining pressures were tested to obtain the damage and rupture sandstone pressure path. CT scan three‐dimensional reconstruction fractured carried out study differences energy evolution during failure pressures. results show that has a significant influence on deformation rock. There is yielding platform for circumferential strain bulk at peak pressure. larger is, greater axial absorption energy,...
A series of tests on characteristics acoustic emission have been performed sandstone under uniaxial, conventional, and triaxial conditions the unloading confining pressure path. The failure mode rock specimen has scanned by CT a three‐dimensional reconstruction was made. differences AE, mechanics, during process three paths are studied. results show that deformation is bigger, axial strain circumferential platform at peak point stress Characteristics AE ringing significantly affected counts...
Wireless power transfer (WPT) is an emerging and promising technique for supplies to mobile portable devices. Among all approaches, magnetic resonant coupling (MRC) excellent one midrange WPT, which provides high mobility, flexibility, convenience due its simplicity in hardware implementation longer transmission distances. In this letter, we consider MRC-WPT system with multiple transmitters, intended receiver unintended receivers. The optimal robust beamforming design of the complex...
Magnetic resonance coupling (MRC) has been utilized in wireless power transfer (WPT) systems to achieve mid-range contactless supply. For many cases, security is an important issue, say when certain users unintended and therefore needs be restricted. Moreover, manufacturing costs physical dimensions are also issues for mass production. In this paper, we investigate MRC-WPT system with multiple transmitters, one intended receiver receiver. We formulate the problem of maximizing by designing...
