Scaling behaviour of a.c. conductivity

Reference was made in the context of universality of the a.c. conductivity behaviour to the Taylor-Isard scaling function. By virtue of scaling behaviour, o co) can be made to collapse on to master curves. Presence of scaling behaviour is indicative of the presence of common 

Since N and T in the above expression are already present in the scaling function of Roling et al. (1997), the scaling expression could be modified as  

conductivities have been measured at infrared frequencies using spectroscopic absorption methods. It is obtained by determining the 

Ultrasonic and Brillouin scattering experiments are also used to evaluate elastic properties of glass using the following relation
