The actuating mechanism comprises an electroplated permanent magnet mounted on a flexible PDMS diaphragm and electroplated Cu coils located on a glass substrate.
The electromagnetic force between the magnet and the Cu coils causes the diaphragm to deflect and then creates the accumulative effects of wave propagation and reflection at the junction of the compressible and rigid sections.
At a frequency of 15 MHz, the resistance of the individual MWCNT-Cu coil was reduced to less than 40% of its original value for primitive Cu, leading to more than a four-fold increase in their quality factor.
When MWCNT-Cu coils were used as the transmitting component, the transmission efficiency of the WPT system increased from 10.57% to 95.81% at a transmission distance of 4 cm and a frequency of 3.45 MHz.
In this study, multi-walled carbon nanotube-coated copper (MWCNT-Cu) coils are successfully introduced to address this limitation by implementing the frequency-inert MWCNT channels along with using their high-surface areas to realize the electromagnetic shielding of the Cu substrate through multiple reflection mechanisms.
The process studied here are expected to be applied to fabricate micro-scale Cu structures, such as coils, antennas, electrical circuits, and wiring and connecting lines if further enhancements of the adhesion ability between layers and the design of pattern fields in a mold are accomplished.
Parameters such as the distributions of nuclear heat density, fast neutron flux, dose rate to the epoxy insulator, and peak displacement dose to Cu conductor for the TF coil near these regions were calculated and analyzed.
In order to prevent a possible refrigerant leakage a special buffer layer filled with the water based Cu nanofluid was mounted in the coil.
The Cu insert allows magnetic field from the three mounted coils to penetrate the interior of the cavity for individual control of all qubits frequencies.
For the pickup coil, we consider the coil made of a cooled Cu wire or an HTS superconductor tape.
For non-magnetic, conductive porous Cu, the electrical conductivity was measured with a calibration curve of the coil relating the impedance change and the electrical conductivity of the sample.
