2003-(II)-Ultrasonic techniques - The Resonator

Written by Iwanowski. Posted in Projects

 Critical systems and total attenuation spectrum:

In the case of critical liquid systems, the ultrasonic spectra get an additional contribution, resulting from the critical fluctuations. This critical attenuation term  has  been treated within  the  framework  of  the  Bhattacharjee-Ferrell  theory.          Assuming  additivity  of  the critical contributions and the other ones, the total ultrasonic absorption spectrum, can be written as:

However,  because  of  its  essential  role  in  these  investigations,  the  first  contribution  of the eqaution will be treated separately in the Project (2003-(III)-Critical Contribution, Dynamic Scaling and Crossover Theory ).
