The broadband dielectric relaxation of a BaTiO3-polymer composite film was studied. The complex dielectric constant data from 10-4 Hz to 1010 Hz reveals the existence of relaxation process at frequency of 10 MHz in the polymer composite. On the basis of Cole-Cole analysis, the relaxation time of the system is of order of 10-8 s. The understanding of the broad dispersion in dielectric behavior of polymer composite materials is needed to support next generation electronic devices used in wireless communication and related applications.
