    This is a schematic of the first-ever plasmomechanical oscillator (PMO), developed by NIST researchers. The orange-white ovals represent the localized plasmon oscillations. The cantilever, containing the gold cuboid nanoparticle, lies dead center. The series of white curves represents the electrical field applied to the cantilever. Data at right indicates that the device can lock onto and greatly amplify weak signals that oscillate at frequencies close to those of the PMO. Credit: B. Roxworthy/NIST
