Abstract:

Expansion of functions in terms of exponential sums is a technique that has been used in the past for applications in applied mathematics such as number theory. However, the technique also has interesting applications in the field of engineering. In this presentation, we shall discuss a novel approach to deriving an expansion of a particular function as an exponential sum and show how this expansion can be applied to the Sommerfeld Integral to give a novel Discrete Complex Image representation of the problem.
