The modelling of plasmonic systems is complicated by the broad range of length scales involved: the physical dimensions of the structure might be as small as 1 nm, whereas the wavelength of the light involved can be a few hundred nanometres. It is now shown that transformation optics, a technique successfully used to design metamaterials, is also valuable for circumventing these problems.
