|POLONSKY Y., POPOV V., BORISOVA M., TSATSYNKIN P., GALJUKOV O.|
The absorption characteristics and thermally stimulated depolarization currents of polyimide films and of mica paper materials with polyimide films were investigated experimentally and analyzed theoretically on the basis of two models: spatial and structural non-homogeneity of the dielectric (or two equivalent circuit). The absorption coefficients of materials were calculated.
