Influence in polarization of cosmic microwave background radiation due to relic gravitational waves

Abstract

According to the prediction of the theory of Big Bang, the universe has gone through from the phase of inflation to the phase of radiation and to the phase of matter at last to the phase of acceleration expansion now. In the radiation phase, the rudimental free photons of decoupling become the Cosmologic Microwave Background Radiation which we observe by now. If there is not any perturbation, the CMB radiation will be isotropy, but in the earlier era of the universe, there exist all kinds of the perturbations, which caused the anisotropy the Cosmic Microwave Background radiation. This research will emphatic depict the influence of the relic gravitational wave for the Cosmic Microwave Background radiation in anisotropy of polarization, especially in E-mode and B-mode polarization.
