Imaging Three-Dimensional Bodies by Processing Multi-Frequency Data Through a Multiscale Swarm Intelligence Based Method

This contribution is aimed at investigating the potentialities and current limitations of the multiscale particle swarm method when processing multi�]frequency data scattered by three�]dimensional structures. Such a global optimization approach demonstrated its effectiveness in solving complex two�]dimensional imaging problems. Therefore, it has been suitably�]modified for dealing with three�]dimensional geometries and integrated into multi�]frequency inversion schemes. Selected numerical results are shown in order to allow a preliminary evaluation of the reconstruction accuracy of the proposed implementations.
