Characterization of objects by weakly electric fish through the first order polarization tensor

Taufiq Ahmad Khairrudin (University of Manchester)

Frank Adams Room 1, School of Mathematics, Alan Turing Building,

According to previous studies by Ammari (2007) and Nelson (2009), electro-sensing by a weakly electric fish has some similarities with the electrical impedance tomography (EIT) system. Because of this we adapted the polarization tensor from EIT into the electro-sensing context. Our aim is to investigate object characterization by the fish through the first order polarization tensor without actually reconstructing an image of the object. In this talk, I will discuss the mathematical background of the polarization tensor in electro-sensing. After that, some examples of object characterization through the tensor by the fish will be given.
