Measuring the shielding effectiveness of superconductive composites

Abstract

The results are presented of a preliminary investigation into the measuring of shielding effectiveness of YBa/sub 2/Cu/sub 3/O/sub 7-x/ both as a composite and as a monolithic material. A flanged coaxial test fixture was selected to measure the shielding. The composite samples showed little or no shielding. The monolithic sample showed substantially less shielding than predicted. Possible explanations for this lack of shielding are discussed.<>
