We developed a cryocooler system to reveal the temperature dependence of the quality ( Q ) factor of high-temperature superconducting (HTS) bulk coil and the power transfer efficiency (PTE) and power handling capability (PHC) of a wireless power tran

The addition of artificial pinning centers has led to an impressive increase in critical current density ($J_{\rm c}$) in a superconductor, enabling record-breaking all-superconducting magnets and other applications. $J_{\rm c}$ has reached $\sim 0.2

We have designed the first superconducting bulk coil for radio frequency (RF) applications. We investigated the effect of the line gap and line width of the coil by simulating the quality factor of the coil for each gap and width. We investigated sev
