Abstract
A simple scheme for compressing the tensors arising in FFT-volume integral equation formulations is reported. The proposed solution is based on the Tucker model and the algorithm originally developed by De Lathauwer et al. [1]. A representative example from the EM analysis of human body models is used to demonstrate the effectiveness of the method; compression of 10, 000x is achieved with approximation error lower than 10-8.
