Numerical methods have become invaluable tools for research in the field of photonics and plasmonics. The Discontinuous Galerkin Time-Domain (DGTD) method, complemented by numerous extensions, allows us to solve Maxwell's equations on unstructured grids while maintaining an efficient, explicit time-stepping scheme. In this contribution we employ our DGTD computer code to analyse dimers of split-ring resonators (SRRs), metallic nano-structures often used as building blocks for metamaterials. We find that electromagnetic coupling between two SRRs heavily influences the dimers' resonances. Results for two SRRs facing each other are presented and the influence of the particle spacing is investigated.
