Abstract
Expressions for the shielding effectiveness of thin superconducting fi lm for near and far held interfering sources have been derived by mode lling the superconductor as a dielectric material of negative dielectr ic constant. Computation of shielding effectiveness of thin film super conductor as a function of frequency is carried out. Results are compa red with those of copper. It is observed that superconductors are bett er shields at lower ranges of millimeter wave frequencies and copper h as a better shielding effectiveness at frequencies beyond 100 GHz.
