چکیده انگلیسی
Simulation is made about ac conductivity, σ(ω), in ion-conducting glass by recurring to one of the Maxwell’s equations. It is concluded that (1) σ(ω) is made of conduction and conduction-related polarization of the mobile ions, both governed by the same relaxation time, τ, and that (2) high frequency dispersion in σ(ω), high frequency dispersion in the electric modulus peak, and distortion of a semicircle in the complex impedance plane, all arise from a distribution in τ, caused by the disordered structure of glass. Finally, a procedure of scaling ac data measured at various temperatures into a single master curve is given.
