Millimetre and sub-millimetre astronomical polarimeters have traditionally been based on birefringent Half Wave Plates (HWPs) used as polarisation modulating elements. Although moderate bandwidth can be achieved using the Pancharatnam designs there are limitations in terms of diameters, weights and associated losses. In addition, the rapid advance in array detector technology at these wavelengths has created a pressing need for large diameter HWPs which exceed those possible with crystalline materials. The first metamaterial HWP was developed using an air-gap mesh filter technology, which demonstrated the feasibility. This was subsequently replaced by a more robust dielectrically embedded version which can be fabricated in much larger diame...
