Polarisation of light can be used to measure orientation of absorbing dipoles, birefringent domains, material re-distribution in complex mixtures at very different spectral domains: from visible throughout infra-red (IR) to sub-mm wavelength at THz frequencies. Polarisation analysis at sub-wavelength scale is a challenging task and requires light-field enhancement using tailored sub-wavelength patterns and/or use of high intensity IR-THz beams at synchrotrons. We overview recent results in polarisation spectroscopy including use of metamaterials.
