In my view, Ludwik has rediscovered a physical effect that is mentioned in
Faraday's Researches... but in very few other places.

It really does seem like a physical penetration of charge into practical
materials, especially evident in bilayer dielectrics. Faraday ascribed
"charge recovery" to the presence of bilayers.

 This is not Maxwell's displacement in my view.
