Nonlinear AC resistivity in s-wave and d-wave disordered granular superconductors

open access: yes, 2002
We model s-wave and d-wave disordered granular superconductors with a three-dimensional lattice of randomly distributed Josephson junctions with finite self-inductance. The nonlinear ac resistivity of these systems was calculated using Langevin dynamical

Eddy current generation enhancement using ferrite for electromagnetic acoustic transduction [PDF]

open access: yes, 2006
Eddy currents are generated in an electrically conducting surface as a step in electromagnetic acoustic transduction (EAT). In eddy current testing, wire coils are often wound onto a ferrite core to increase the generated eddy current.

Eliminating Inductive Coupling in Small-Loop TEM Through Differential Measurement with Opposing Coils

open access: yesRemote Sensing
The small-loop transient electromagnetic method (TEM) refers to a system in which the coil frame length or diameter is less than 2 m. Due to the inductive effects of the multi-turn coils used for both transmission and reception, the induced electromotive

Bloch inductance in small-capacitance Josephson junctions

open access: yes, 2005
We show that the electrical impedance of a small-capacitance Josephson junction includes besides the capacitive term $-i/\omega C_B$ also an inductive term $i\omega L_B$. Similar to the known Bloch capacitance $C_B(q)$, the Bloch inductance $L_B(q)$ also
