Superconductors have been considered for electromagnetic shields in large systems which can justify the expense of cooling with liquid helium. The advent of higher critical temperature superconductors has allowed investigations into their possible implementations in smaller systems which can only justify the cost of less expensive liquid nitrogen. This new type of superconductor is quite brittle and mechanically difficult to handle. One solution to this obstacle might be to mix superconductive powder in a plastic matrix. This paper presents the results of a preliminary investigation into the magnetic shielding effectiveness of the YBa/sub 2/Cu/sub 3/O/sub 7-x/ superconductors both mixed in a plastic matrix and as a pure ceramic. However, before the discussion of superconductive shielding, a short review of a couple of traditional shielding concepts might be appropriate. 8 refs., 3 figs.
