We have performed measurements of Z' and Z" in YBaCuO-Ag nonrandom composites. Results of Z' vs. temperature show a strong reduction of intra-granular shielding in the superconducting composites. Cooling the samples in large superimposed DC fields, measurements of g' and g" at fixed temperatures as
