Contact Details for Dr Andrew Seagar
Research expertise
Dr Seagar has expertise in the areas of computational electromagnetics and biomedical engineering.In the area of computational electromagnetics he specialises in the use of conventional boundary integral techniques for the calculation of the fields surrounding high tension power transmission lines, and the newer multi-dimensional Cauchy integral technique using Clifford algebra for the fields scattered from perfectly reflective and partially transmissive objects.
In the area of biomedical engineering he focusses on the application of signal and image processing as an aid to medical diagnosis and treatment.
Current teaching areas
