Particle Density Retrieval in Random Media Using a Percolation Model and a Particle Swarm Optimizer

This letter is a rst attempt to apply a percolation theory model to the estimation of the density of particles in complex layered two-dimensional media from electromagnetic measurements. A procedure based on an analytical closed-form description of the wave propagation process is presented. The problem is recast as an iterative optimization one and solved by means of a particle swarm optimizer. Numerical experiments show the validity of the proposed solution. (c) 2007 IEEE.
