Transforming Light and Sound With Metamaterials
Recently, exciting new physics and applications are emerging from
metamaterials made of artificial “atoms” and “molecules”. These
metamaterials has inspired a series of key explorations to manipulate, store and control the flow of energy at unprecedented dimensions. Yet, these ground-breaking achievements are only the tip of the iceberg, where the next-generation metamaterials, incorporating unique topological interactions between waves and matter, are waiting to be discovered.
In this talk, I will discuss our progress of fabrication and
characterization of these optical and acoustic metamaterials. We
demonstrated, for the first time, focusing and rerouting ultrasound
through broadband and highly transparent metamaterials. We also observed a set of localized modes in optical metamaterials, using novel near field optical and electron probes. These novel metamaterials, could be the foundation of broadband photo-absorbers, directional emitters, as well as compact and power-efficient devices in highly parallel optical networks.
