Abstract :
In this invited talk, we present the fabrication and characterization of optical and acoustic metamaterials, incorporating unique topological interactions between waves and matter. We propose spatially 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.
