Ultrasensitive Non‐Resonant Detection of Ultrasound with Plasmonic Metamaterials. (1st March 2013) - Yakovlev, Vladislav V.
Abstract Optical sensors for ultrasound detection provide high sensitivity and bandwidth, essential for photoacoustic imaging in clinical diagnostics and biomedical research. Implementing plasmonic metamaterials in a non‐resonant regime facilitates sub‐nanosecond, highly sensitive detectors while eliminating cumbersome optical alignment necessary for resonant sensors.
