Can we do math and solve equations with metamaterials?
Metastructures have provided a fascinating platform for unprecedented light-matter interaction with a wide variety of potential applications. Numerous exciting features and phenomena enabled by wave dynamics in metastructures have been introduced and developed in recent years. One such feature is the possibility of performing mathematical operations and signal processing with metamaterials [A. Silva, F. Monticone, G. Castaldi, V. Galdi, A. Alu, and N. Engheta, “Performing mathematical operations with metamaterials,” Science, 343, 160-163 (2014); A. Vakil and N. Engheta, “Fourier optics on graphene,” Phys. Rev. B 85, 075434 (2012)]. By properly juxtaposing metastructures with different material properties, we can design “circuits with light at the nanoscale” and we can conceive of platforms that can perform mathematical operations and solve equations. In other words, materials can act as “circuits” and materials can do math. In my group we have been developing this concept, and currently we are conducting research on metamaterial platforms that can solve the Fredholm integral equations of the 2nd kind. We are considering two different categories of structures, i.e., inhomogeneous platforms and Mach-Zehnder interferometer (MZI) meshes. In this talk, I will present some of the latest results of our onging work on metamaterial-based analog computing and information processing.

Merging micro- and nano-optics: Fundamental aspects and applications
Plasmonic nanostructures enable extreme subwavelength concentration of light. This has led to many exciting new avenues in linear and nonlinear optics as well as in sensing.
Highly nonlinear optical processes can lead to electron emission from atomically flat plasmonic surfaces. This reveals the subfemtosecond dynamics of plasmon focusing to 60 nm and subsequent vortex formation. Higher orbital angular momenta can be confined to below 100 nm, possibly suited for nondipolar interaction with large individual quantum systems (see left picture).
On the micro-scale, femtosecond 3D printing opens a new avenue in micro-optics. Arbitrary freeform and aspheric shapes can realize high-quality and even diffraction-limited imaging systems as well as multi-element microscope objectives for endoscopes and sensors with sizes of only a few hundred micrometers (see middle and right picture). When combined with active nano-optical elements, beam shifting, scanning as well as zooming can be realized without any moving parts.
Combining micro- and nano-optics will serve as enabling technology for understanding fundamental material science questions as well as realizing optical, chemical, biological and medical applications in the future.
