摘要:
An apparatus is described which can be used to measure the velocity of Rayleigh waves and direction of energy flow throughout any given plane in a piezoelectric material. Some results are presented for part of theX‐Zplane in lithium niobate. Additionally, with the use of a thin film transducer the measurements can be extended to non‐piezoelectric materials.
