Dear Debanjan,

From your data you can produce Cole-Cole plot in Z plane (-imaginary impedance in y-axis and real impedance in x-axis). Just calculate Zcos(theta) in x-axis and -Zsin(theta) in y-axis. It is important that 'theta' is in degree and your calculation must be in degree mode (if you are using calculator or by software). But, from these data, no information about dielectric values can be read. Hope this will be helpful.
