Meissner screening profile for superconductor-insulator-superconductor (SIS) multilayer.

The expression was derived from a London model of the SIsS layers.

See Eqs. (1) to (3) in: T. Kubo et al. Appl. Phys. Lett. 104, 032603 (2014). https://doi.org/10.1063/1.4862892

Parameters:

  • x – Depth below the suface (nm).

  • B_0 – Applied magnetic field (G).

  • d_S – Superconducting film thickness (nm).

  • lambda_1 – Magnetic penetration depth of the superconducting film (nm).

  • d_I – Insulating layer thickness (nm).s

  • lambda_2 – Magnetic penetration depth of the superconducting substrate (nm).

Returns:

The Meissner screening profile at position x (G).
