Polarization Characteristics Of Radiation Transfer By Vector Monte Carlo Method

In the field of heat radiation transfer, lots of scholars and research institutionsdid many jobs in scalar radiation transfer (SRT) research in past years, so SRT hasdeveloped quite maturely. There are many numercial method to solve SRT now.With the research deep going and the need of accurate results, the polarized effect isnot to be neglected in some conditions. In recent years, polarized radiation transferbecome to be the key point in research gradually.This paper uses the Stokes Vector to describe the polarized light, and usesMonte Carlo Method (MCM) to solve vector radiation transfer (VRT). It gives ushow to use MCM to solve VRT. It uses rejection method to calculate the scatterangles, and gives us how to get these angles in detail. This paper also puts forwardusing normalized Stokes Vector to describe the transfering photons and itspolarization information. It defines a new coefficient, vector radiation transfercoefficient. It did comparison with related articles to one-dimensional model, andverifying the model is right. This paper also gave us the three-dimensional modelsimulated result.In the last part, this paper researched the VRT apparent emission characteristics,and did comparison with SRT results. It comes up with the definition of vectorradiation transfer factor and Stokes apparent emission characteristics. It did researchto the apparent emission characteristics of semi-transparent medium in detail. Also,this article has explored the time effect about the VRT, and has verified the accuracyof the model.
