Question

What do you mean by Flux Exclusion?

Answer 1

Explanation:

We will call this design the flux exclusion quantum metamaterial. For normal radiation incidence on the array of such meta-molecules, the magnetic field of the incident wave does not penetrate the array and therefore is not directly engaged in the flux quantization

Answer 2

Answer:

The Flux Exclusion in Superconducting Ring. ... At low amplitudes of the applied field, the amplitude of the total flux through the loop |Φ| stays close to zero. When the amplitude of the applied field increases to a critical value B*, the amplitude of magnetic flux through the loop jumps to one flux quantum Φ0.
