Electromagnetic simulation tools play an important role in the fields of nanoplasmonics and metamaterials, where breakthroughs are frequently slowed down by the limited power of these tools when addressing real-life problems. We herein show that boundary element variational methods, along with the hierarchical spectral compression of the multilevel fast multipole algorithm (MLFMA), can effectively model the interaction of light with large nanoplasmonic metamaterial assemblies, raising the standard of full-wave simulations in the field of nanoplasmonics to an unprecedented level.

We developed two complementary printing techniques based on nanotransfer printing and imprinting that are directly applicable to fabrication of 3D metamaterials with excellent optical characteristics, in ways that are scalable to arbitrarily large areas and compatible with manufacturing.

The structural plasticity and interaction encoding provided by DNA offer enormous opportunities for directing the nano-objects into precisely structured architectures. Such architectures might coordinate nanoparticles of multiple types in the designed manner, and they might be transformed on demand. Toward these goals, we have developed a range of methods for assembly of well-defined nanoparticle clusters and arrays using the DNA-assembly platform, explored how the structures can be manipulated, and applied these approaches for the fabrication of optically active systems.

15:40 Invited talk : Building Metamaterials Using Scalable Self-Assembly Techniques

Andrea Tao

University of California (USA)

I will present our recent work on the synthesis and self-assembly of nanocrystals for plasmonic metamaterials. We show the organization of polymer-grafted metal nanocrystals into nanojunction arrays that possess intense hot spots due to electromagnetic field localization. We also demonstrate doped semiconductor nanocrystals as a new class of plasmonic building blocks, where shape and carrier density can be actively tuned to engineer plasmon resonances. We are utilizing these self-assembled metamaterials in applications such as near-field spectroscopy, biosensing, and optoelectronics.
