    Abstract

    According to an aspect, there is provided a structure comprising an absorbing layer (108, 401) for absorbing incident infrared radiation received via a receiving surface (107, 404) of the absorbing layer (108, 401) and a plurality of mushroom-shaped plasmonic elements (104) for enhancing absorption of the incident infrared radiation into the absorbing layer. Said plurality of mushroom-shaped plasmonic elements (104) have sub-wavelength dimensions and sub-wavelength spacings and are arranged along the receiving surface (107, 404). Each of said plurality of mushroom-shaped plasmonic elements (104) project out relative to the receiving surface (107, 404).
