Penetration equation metals
The London equation can be shown to require that the magnetic field exponentially decays to zero inside a superconductor see Meissner effect discussion. Not so when you switch over to the Sr source. This phenomena is shown in Figure 1. Where k describes the efficacy of a metal for light damping. Metals are known for having high reflectivity, which explains their shiny appearance.
α, β, γ Penetration and Shielding
By relating the London equation to Maxwell's equations , it can be shown that the Meissner effect arises from the London equation. However, all short-circuited samples exhibited lithium penetration originating at the perimeter of the gold working electrode, away from the introduced defects. This leads to a decrease in reflectivity, which depends on the metal's characteristics. Finite element modeling was used to investigate the magnitude of field enhancement as a function of the relative sizes of the positive and negative electrodes, and the thickness-to-width aspect ratio of the cell. However, in the course of investigating the effects of large controlled flaws, we discovered that variations in current density due to the geometric configuration of surface current collectors can have a larger, dominant effect on lithium penetration.

Penetration depth - Wikipedia
The table below gives some specific values. Here, it appears that the fracture resistance for the extension of an unfilled crack is lower than that for one filled with lithium. At this temperature, the conductivity of pure copper is 5. This image reveals the initiation sites for lithium penetration at the sc-LLZTO surface beneath the gold WE, the perimeter of which is outlined in white. C gives off betas with a maximum energy of 0.
Complex relationships between heating efficiency and particle size have been reported, and vary from metal to metal related in part to the presence or absence of surface dielectric layers 2, 3. Plug in the known values and solve. As the weld metal solidifies, the shrinkage stresses are thus fairly uniform in all directions. A deeper and broader penetration profile covers a bigger area. It has to do with the fact that the superconducting electron density cannot change quickly - there is a minimum length over which a given change can be made, lest it destroy the superconducting state.
