- Description
- The scattering matrix or S-matrix is a widely used tool in many branches of physics and engineering and it gives a simple way to encapsulate the complex behaviour of a system which is characterized by the relationship between the incident and the scattered waves. It has proved to have many useful properties, for example the poles of the S-matrix in the complex-energy plane can be identified with bound states, virtual states or resonances. The authors have recently developed numerical methods which allow the analytic extension of wave scattering calculations for cylindrical wave energy converters (WECs) into the complex plane. We use this computational tool to investigate the poles of the S-matrix and show that these are identified with the near-trapped or resonant states for WECs. We give visualizations of the S-matrix. These results, while highly theoretical, have application in determining the wave response of WECs and could assist in the design of optimal arrangements.
