The study is undertaken in the microwave regime, where the cm scale of the metamaterial analogue provides an opportunity to directly probe the modes deep within their near-fields in ways not easily achieved in molecular systems. To demonstrate the power of this approach we compare our observations to predictions from a simple Su, Schrieffer and Heeger (SSH) model, and find good qualitative agreement.Engineering and Physical Sciences Research Council (EPSRC)Engineering and Physical Sciences Research Council (EPSRC)European Research Council (ERC
