Wireless power transfer in magnetic resonance imaging at a higher-order mode of a birdcage coil

, 2023
Magnetic resonance imaging (MRI) is a crucial tool for medical visualization. In many cases, performing a scanning procedure requires the use of additional equipment, which can be powered by wires as well as via wireless power transfer (WPT) or wireless ...

Photoemission study and band alignment of GaN passivation layers on GaInP heterointerface

, 2023
III-V semiconductor-based photoelectrochemical (PEC) devices show the highest solar-to-electricity or solar-to-fuel conversion efficiencies. GaInP is a relevant top photoabsorber layer or a charge-selective contact in PEC for integrated and direct solar ...

Two concurrent exponential decays in a vacuum capacitor-resistor circuit: effect of surface charge

The relaxation in a vacuum capacitor-resistor circuit is comprised of two exponential decays, one caused by surface charge and the other by the decay of energy stored between the capacitor plates.

Non-Invasive Readout of the Kinetic Inductance of Superconducting Nanostructures

The energy landscape of multiply connected superconducting structures is ruled by fluxoid quantization due to the implied single-valuedness of the complex wave function.

Holographic Thermal Mapping Using Acoustic Lenses

Acoustic holographic lenses (AHLs) show great potential for sound manipulation. These lenses store the phase and amplitude profile of the desired wavefront when illuminated by a single acoustic source to reconstruct focused ultrasound (FUS) pressure ...
