Popis:	We report the modifications in the structural and dielectric properties of polycrystalline Bi1-xCaxFeO3 (BCFO) (x = 0.05, 0.10, 0.20) multiferroics understood in the context of grain and grain boundary contribution to the complex impedance and modulus behavior. It is seen that, in BCFO with increase in Ca-concentration, the insulating nature of both, grain and grain boundaries gets enhanced. Analysis of the Nyquist plots confirm the presence of non –Debye type relaxation in all the Ca-doped BCFO samples.
