The group is involved in long-term collaborative work with Prof Richard Craster of the Department of Mathematics at Imperial College, to develop the mathematical basis and solutions for wave phenomena. Projects which have been conducted include the development of models for the propagation of ultrasound around curved waveguides, the study of trapped modes at structural features such as bends, the efficient calculation of the properties of guided waves, and the development of efficient numerical procedures for simulating wave propagation. Additionally, via the collaborative link, the mathematicians provide mathematical support to the group for specific problems as they arise.
