We develop Polnarev’s analytic method to calculate of the polarization power spectrum of the cosmic microwave background radiation (CMB) generated by cosmic relic gravitational waves. In this analytic approach the physics involved in this process is more transparent. Consequently, the effects due to various elements of physics can be isolated easily. In numerically calculating the evolution of the gravitational waves during the radiation-matter transition, the WKB approximation for the scale… CONTINUE READING
