Electric field Monte Carlo for simulation of multiple scattering polarized light | |
Light multiple scattering is commonly studied using Monte Carlo simulations. The
deficiency of conventional Monte Carlo methods is their lack of information about
the phase of light and is not suitable for the study of coherence phenomena. A
novel electric field Monte Carlo (EMC) method for simulation polarized light
propagation in turbid media has recently been developed by us [1, 2]. The EMC
method is different from conventional Monte Carlo approaches. EMC simulates
the propagation of the electric field directly and hence contains the complete
phase of light when it propagates in a turbid medium, accrued from both
scattering by particles and propagation in the medium. This makes EMC a unique
Monte Carlo approach able to study phase correlation and coherence effects of
multiple scattering light in a first principle way. One example is the EMC study of
coherent backscattering of polarized coherent light by a turbid medium
[3].
NEW: Electric field Monte Carlo package (EMC) version 0.6 can be found here. A brief introduction to EMC is given in README.txt included in the package. Please study the example deplength.cpp included in the package carefully. This simple example demonstrates the basic usage of EMC package. Two other examples are also included which were presented in the EMC paper. Selected Publications
