CMB Quadrupole induced polarisation from clusters and filaments
  We present the estimates of the Cosmic Microwave Background (CMB) polarisation power spectrum from galaxy clusters and filaments using hydrodynamical simulations of large scale structure formation. We focus in the present study on the CMB Quadrupole induced polarisation, which is the dominate secondary polarisation effect, and give the E and B mode power spectra between $l \sim 560$ to 20000.
