OPTICAL-PROPERTIES OF CERMETS - 3D REAL-SPACE RENORMALIZATION USING THE CONNECTION MACHINE

We propose a 3D position space renormalization approach based on Kadan offs block method, for the calculation of the effective dielectric fun ction of cermet type film. This model has been applied to simulated cu bic lattices with particle aggregation. Our calculations were performe d on a Thinking Machine CM5 massively parallel supercomputer. The reno rmalization process maps very naturally on to hypercube parallel archi tecture. We obtain good agreement with most of the experimental data.
