| Abstract: |
| Concentrating light at the nanoscale is one of the greatest challenges in optics. Using conventional optical devices, light cannot be focused into a spot smaller than a few hundred nanometers due to the diffraction limit. Nano-optics overcomes this fundamental difficulty by using optical nanostructures with close-to-touching inclusions. In such structures, light can be strongly localized in the narrow gap regions between the inclusions. In this talk, we discuss how to characterize the singular behavior of waves scattered by close-to-touching inclusions, and its implication for the inverse design of nano-optical devices. |
