What Cavities in Superconductors Reveal About Superconductivity
Annalen der Physik, Volume 538, Issue 5, May 2026.When a normal metal with one or more small cavities in its interior is cooled into the superconducting state in the presence of a magnetic field, will it expel the entire field to reach its lowest energy state? The conventional theory says yes, the theory of hole superconductivity says no.

AN EXTENDED DELAY-RATIONAL MACROMODEL FOR ELECTROMAGNETIC INTERFERENCE ANALYSIS OF MIXED SIGNAL CIRCUITS [PDF]
Progress In Electromagnetics Research, 2012 This paper presents an extended delay-rational macro- model for electromagnetic interference analysis of mixed signal circuits. Firstly, an S-parameter matrix based delay-rational macromodel of the associated microwave network or system is established. Then, we extend the macromodel to include the external electromagnetic inter- ference efiects.
