Unified Pressure and Field Response Across Distinct Charge‐Order Regimes in Ti‐Doped CsV3Sb5
Advanced Functional Materials, EarlyView.We microscopically investigate the interplay between charge order and superconductivity in a kagome superconductor across regimes of long‐ and short‐range charge order. Hydrostatic‐pressure and magnetic‐field μSR$\mu{\rm SR}$ measurements reveal remarkably similar superconducting and normal‐state time‐reversal‐symmetry‐breaking responses in both ...

Efficient Power Transfer to Implanted Antennas
IEEE AccessWireless power transfer between an external electromagnetic source and implanted dipoles into the human body can be greatly assisted by employing a matching part atop of the skin. Two different approaches are proposed: one incorporating lossless layers that minimize the reflections and another dealing with active metasurfaces that boost the ...
