We used a stack of meta-molecules based on split ring resonators (right) to mimic linear (J- and H-) aggregates. Using RF techniques we measured the dispersion of the modes (left)


Project photmat is all about linking molecules with light. We have recently added a new way to explore this exciting science by showing that we can mimic such processes in the microwave regime by making use of metamaterials, a more detailed description is here, and the published article here. Many of the properties we would like to investiagte need to be resolved at the molecular scale, for example: is energy localised by defects? can we see what happens to individual molecules when they are strongly coupled to an optical mode? Exploring these questions with real molecular systems usually involves optical probes, and – in general – optical probes do not have the required spatial resolution. In recently published work we have established a new approach by making use of metamaterials to mimic coherent molecular effects. The experimental work was primarily carried out by PhD student Milo Baraclough, a member both of photmat, and our PhD centre for metamaterials.
