Abstract

The object of this work is to investigate the microwave absorbing properties of nanocomposite bulk samples. As filler we used magnetite with different particle size in a silicone rubber matrix and investigated the influence of the filler concentration and particle size in the polymer matrix on the microwave nonlinearity in a large frequency range (1 Γ· 13 GHz). We found that the intensity and the frequency at the reflection loss minimum depend on the particle size and particle concentration of magnetite in the samples. (Β© 2006 WILEY‐VCH Verlag GmbH & Co.

A systematic study of the relationship between particle dimensions and microwave absorption in micron size powders of superconducting Y~Ba2Cu307 reveals that small particles have negligible absorption at T< 0.8 To, and that the transition gets sharper as the grains get bigger. However, when the part
