Cubic-type fused silica is characterized by the following elastic and relative permittivity constants: c11 = 7.85 × 1010N/m2 , c44 = 3.12 × 1010N/m2 , c12 = 6.39 × 1010N/m2 and ε11 = 11.7 × ε0. The...

Cubic-type fused silica is characterized by the following elastic and relative permittivity constants: c11 = 7.85 × 1010N/m2 , c44 = 3.12 × 1010N/m2 , c12 = 6.39 × 1010N/m2 and ε11 = 11.7 × ε0. The density of the material is ρ = 2332kg/m3 . Calculate the Rayleigh SAW velocity. The direction of propagation is the x axis, and the free surface is normal to the z axis. [Hint: You may employ a displacement formulation
