Abstract
We present simulations of the polarised radio sky at Square Kilometre Array (SKA) wavebands. Further, we discuss how measurements of linear polarisation can be used to explore intrinsic source polarisation properties and to study the magnetic fields of galaxy clusters via Faraday rotation of the polarisation plane. For this purpose, we consider source and cluster models of differing complexity. We make forecasts for the SKA. By applying Bayesian statistical analysis methods, we quantify constraints which can be placed on source polarisation properties and cluster magnetic fields.
