Wireless power transfer using Class E inverter with saturable dc-feed Inductor [PDF]

, 2014
Resonant converters used as coil drivers in inductive links generally operate efficiently at optimum switching conditions for constant load values and ranges. Changes in load and range can shift the operation of the coil driver to a non-optimum switching

Global inductive magnetosphere-ionosphere- thermosphere coupling [PDF]

Annales Geophysicae
The ionosphere forms the inner boundary of near-Earth space, where collisionless space plasma transitions into a partially ionized gas that interacts with the neutral atmosphere through collisions.

Nonclassicality of open circuit QED systems in the deep-strong coupling regime

New Journal of Physics, 2021
We investigate theoretically how the ground state of a qubit–resonator (Q–R) system in the deep-strong coupling (DSC) regime is affected by the coupling to an environment.

Modeling and behavioral analysis of neurons under direction-dependent resistive, inductive and capacitive coupling

Results in Control and Optimization, 2021
This study exploits the modeling and behavioral analysis of electrical coupling medium between neurons. A new electrical coupling model that represents two resistor, inductor and capacitor (RLC) circuits for a single link between two neurons is ...

Tuning class E inverters applied in inductive links using saturable reactors [PDF]

, 2014
This paper investigates the performance of Class E inverters used in wireless power transfer applications based on resonant inductive coupling. The variations in the load and the distance between the coils cause Class E inverters to operate in non ...

Electronic tuning of misaligned coils in wireless power transfer systems [PDF]

, 2014
The misalignment and displacement of inductively coupled coils in a wireless power transfer system (WPT) can degrade the power efficiency and limit the amount of power that can be transferred.

A Novel Coupling Mechanism for CSRRs as Near-Field Dielectric Sensors

Sensors, 2022
This work proposes a novel coupling mechanism for a complementary split-ring resonator as a planar near-field microwave sensor for dielectric materials. The resonator is etched into the ground plane of a microstrip line.
