Scientific paper

We present a fast, arbitrarily accurate method to simulate the effect of
gravitational lensing of the Cosmic Microwave Background anisotropies and
polarization fields by large scale structures. We demonstrate the efficiency
and accuracy of the method and exhibit their dependence on the algorithm
parameters.
