Superconducting windows for electromagnetic screening

摘要

A method and apparatus for temperature activated protection of electronic components from interfering electromagnetic radiation comprising the step of shielding of a component with a thin film of superconducting material characterized by a critical temperature of at least 93 DEG K, and exposing the film to a temperature below the critical temperature. To allow transmissions to and from the component, the shield is converted to a window by heating the film to a temperature above the critical temperature.
