Direct observation of defect modes in molecular aggregate analogues (dataset)

In this work we investigate defect modes localised at the ends and within the bulk of 1D metamaterial analogues of molecular aggregates. 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.
