Disorder tolerance of meta-atoms supports self-assembled bio-templating approach for macroscopic scaling.
- Bottom-up self-assembled metallized-DNA meta-atoms are a viable approach for large-scale optical metamaterials but are prone to significant disorder and surface roughness.
- Our aggregated-random-spheres model simulates the growth and response of metallized-DNA split ring resonators (SRR).
- Demonstrates useful resonances are still observed even when dramatic disorder is introduced. Demonstrating a high level of robustness of the optical responses of these deeply sub-wavelength meta-atoms.
