Abstract

Expressions for the shielding effectiveness of thin superconducting film for near and far field interfering sources have been derived by modelling the superconductor as a dielectric material of negative dielectric constant. Computation of shielding effectiveness of thin film superconductor as a function of frequency is carried out. Results are compared with those of copper. It is observed that superconductors are better shields at lower ranges of millimeter wave frequencies and copper has a better shielding effectiveness at frequencies beyond 100 GHz.
