Experimental investigation of bounded beam reflection from plane interfaces in the vicinity of leaky waves angles
The aim of this work is an experimental validation of the reflected and transmitted fields through a viscoelastic material when a bounded ultrasonic beam is incident at different angles. Special measurements are carried out when incidence is performed at some critical angles of the material used. So the propagation of leaky waves along the solid layer is investigated. The inverse procedure for optimizing model parameters from the noisy input-output data is performed using the maximum likelihood estimator.
