AbstractIn this paper, we revisit the weak gravitational lensing of the cosmic microwave background (CMB). The key point is that the deflection angle of CMB photons varies with the redshift. From this we obtain a set of modified power spectra. Compared with those calculated previously, the temperature, the polarization E mode, and the cross power spectra correction are of the order 0.01%, while the polarization B mode correction is about 0.4% (to l = 2000).
