Abstract

The technique of artificial absorbing boundaries is often applied in the numerical modelling of wave propagation and other related numerical studies of ultrasonic NDE. For a physical problem with an unbounded spatial domain, the introduction of artificial boundaries to bound the computational domain can be vital for a successful numerical solution. Even for problems with bounded spatial domains, the introduction of artificial absorbing boundaries that localize the area of interest can reduce the computing cost and allow limited computer resources to achieve more. It is particularly so in ultrasonic NDE where the field near the scatterers or transducers is normally of interest.
