Technologies that rely on interactions between matter and polarized light usually stick to the well-understood effects of linear or circular polarization. Researchers at Rice University in the US have ...

Filters transmit some colours of light and absorb other colours of light. Colours which are transmitted pass through the filter and come out the other side. Colours which are absorbed do not pass ...
