(1) Ultrasonic waves in multilayered superconducting plates (See Pan, E. and Datta, S. K. (1999): Ultrasonic waves in multilayered superconducting plates. Journal of Applied Physics, 86: 543-551.)

The figure on the left hand side shows comparison of dispersion curves for a homogenous nickel plate and a three-layer YBCO/Ni/YBCO plate; The figure on the right hand side shows e-domain Green'displacements for a homogenous nickel plate and a three-layer YBCO/Ni/YBCO plate.
