So first, we will introduce what is the circular birefringence of material. 1.2 The concept and the mathematical expression of circular anisotropy In nature, there are many materials with asymmetric structure have anisotropic dielectric permittivity, which causes the optical anisotropy.
Some materials have a special optical properties, their absorption coefficient or refractive index are not the same for left and right circularly polarized lights, which is called as optical circular anisotropic media, also including the circular dichroism and circular birefringence.
For isotropic materials, al=ar and nl=nr.

This means that they are renewable materials, which are biodegradable and therefore can be easily recycled.
These problems can be avoided by using pulp or paper fibers for reinforcing thermoplastic matrix materials.
Materials and Methods All composites were fabricated with polypropylene (PP) HD 120 MO as a matrix polymer.

Numerical simulation of flash butt welding of high manganese steel crossing with carbon steel rail Yanguo Lia, Fucheng Zhangb Corresponding to: Fucheng Zhang（zfc@ysu.edu.cn） State Key Laboratory of Metastable Materials Science and Technology, Yanshan University, Qinhuangdao 066004, Hebei, P.
The model considers comprehensively the physical parameters of materials, which change with temperature, as well as the burning material caused by the splutter during welding process.
However, there are big differences between these two kinds of materials in physical properties, metallographic microstructure as well as weldability.
With stainless steel as a welding media, flash butt welding appears successful in welding these two materials[1,2].
