> The coil system consists of a receiver coil
, which is implanted under the skin, and a transmitter coil, which is positioned on the skin outside the body
The process simply involves setting your phone down on a flat charging mat, during which the charger emits an alternating magnetic field that induces an alternating current in a receiver coil
to the device...
In order to consider any region to be near-field, two conditions should be considered: first, the distance between the transmitter and receiver coil
(r) should be less than one wavelength ([lambda]) at the operating frequency (r < [lambda]), and secondly, the largest dimension of the transmitter coil should be less than [lambda]/2.
The magnetic induction type wireless transmission system used in this study receives electric induction between the transmitter coil and the receiver coil
. When a magnetic field is generated in the transmitter coil, the receiver coil
receives the magnetic field and induces the electric power.
A pad in the garage floor transfers the power to a receiver coil
in the car with a power output of 3.6 kW.

Depending on the permeability of the test part, the magnetic flux induces a distorted signal in the receiver coil
. Fourier analysis of the distorted signal reveals harmonics of the 3rd, 5th, 7th, and 9th order.
The aim is to transfer energy wirelessly from transmitter coil to receiver coil
based on magnetic resonance.
With the same conclusion as in , with the two receiving coils, the overall transmission efficiency of multiple receive coils is higher than that of a single receiver coil
, but as the number of receivers increases, the overall efficiency of the system tends to saturate and the efficiency of each individual receive coil becomes very low.
This method reconstructs the missing k-space data in each receiver coil
using convolutional kernel estimated from the fully acquired autocalibration signal (ACS).
