This book presents some new results in the studies of anomalous electromagnetic properties of thin granular carbon films. The book describes the study of some new anomalous electromagnetic effects in graphite-like thin carbon films. These are: The fast switching (10-9 sec) of electrical conductivity; The detection of microwave radiation and its temperature dependence; The oscillations of film stack magnetisation in a magnetic field of 1-5 T; The generation of optical radiation during the spasmodic switching of conductivity.
