Pearl inductance in thin films of YBCO enables terahertz superinductance and achieves impedance surpassing the quantum resistance limit, promising advancements in quantum and photonic technologies.

Baile Cui and colleagues present a surface acoustic wave chip based on the acoustic impedance effect for gas sensing with a wide range (1–100 v/v%) and sub-second response and recovery.

Therefore, a two-stage adaptive virtual impedance-based current limitation for improved grid-supporting capability is proposed. Theoretical analysis shows that the better response performance of ...
