The nonlinear dielectric property of the ferroelectric Sr0.61 Ba0.39 Nb2 O6 (SBN) crystal is essential to device application at various frequency ranges. The dielectric constant of the SBN single crystal fiber was investigated at x band microwave frequency using the resonant cavity perturbation method. It was found that compared with large and decreasing dielectric constant of SBN at low frequency, the dielectric property of the SBN crystal at x band frequency was smaller with similar value controlled by dipole orientation or atomic vibration.
