This technical report comprises ten publications on the reflection of ultrasonic waves at liquid-solid interfaces. Description is given of both experimental and theoretical advances in the understanding and utilization of reflection phenomena. Attention is concentrated primarily on the angles at which leaky surface waves are excited along the interface. Rayleigh angle phenomena are described, as well as the backward shift resulting from a periodicity superimposed on the interface. Utilization of these phenomena in nondestructive evaluation and in underwater acoustics is mentioned.
