Using Green’s function method, microwave lossess were theoretically calculated for BaTiO3, SrTiO3 and KTaO3 ferroelectric perovskites. In microwave range, an increase in frequency is followed by an increase in the dielectric loss. In the paraelectric phase, the dielectric loss decreases with increasing temperature showing the Curie-Weiss behaviour of the tangent loss.
