Abstract
According to an aspect, there is provided a structure comprising an absorbing layer for absorbing incident infrared radiation received via a receiving surface of the absorbing layer and a plurality of mushroom-shaped plasmonic elements for enhancing absorption of the incident infrared radiation into the absorbing layer. Said plurality of mushroom-shaped plasmonic elements have sub-wavelength dimensions and sub-wavelength spacings and are arranged along the receiving surface. Each of said plurality of mushroom-shaped plasmonic elements project out relative to the receiving surface.
