Abstract
Interface acoustic waves (IAWs), also known as Stoneley waves, are theoretically and experimentally investigated in a multilayer platform consisting of Y-rotated, X-propagating LiNbO3, an SU-8 guiding layer, and a silicon substrate. Two distinct IAW modes with different phase velocities are identified. Numerical simulations and experimental measurements confirm the efficient electroacoustic excitation of the Stoneley modes.
