Technique for measuring the parameters of polarization of an ultrasonic   wave
  Method for precise measurements of the ellipticity and rotation of the polarization of a transverse ultrasonic wave is presented. It is applicable for investigating the acoustic analogs of the Faraday, Cotton-Mouton, and Kerr effects. The technique consists of measuring amplitude of the voltage on the receiving piezoelectric transducer at a certain magnetic induction B, relative to an initial one using three different positions of the transducer with futher processing the data with the formulars given in the paper.
