Abstract
This paper uses inverse adding-doubling (IAD) method and Monte Carlo method for the simulation of the spectral angular transmittance of a novel kind of thermotropic material at different temperatures. The results show that the collimated light takes the major part at the beginning of the switching process and the scattered light is negligible. However, the scattered light increased to high above 80% of the total transmitted light with the largest angle distribution of scattered light about 30 degrees as temperature elevated.

This paper uses inverse adding-doubling (IAD) method and Monte Carlo method for the simulation of the spectral angular transmittance of a novel kind of thermotropic material at different temperatures
In our previous work [2] a novel kind of thermotropic material was developed for energy efficient windows, and the radiation transmittance measurement showed that it has a better performance than Low-e double-glazed windows
The optical properties of a turbid medium are characterized by the absorption coefficient, the scattering coefficient, and the anisotropy coefficient (g) [13]
Summary
This paper uses inverse adding-doubling (IAD) method and Monte Carlo method for the simulation of the spectral angular transmittance of a novel kind of thermotropic material at different temperatures. This paper adopted IAD method to determine the optical properties of the thermotropic material, and its results were used as the inputs of Monte Carlo simulation.
