High-frequency electrical nerve modulation employs kilohertz-range alternating currents or bursts to achieve reversible and local control of neural conduction. By exploiting biophysical interactions ...

Acousto-optic modulation leverages the interaction between sound waves and light to control optical properties such as frequency, phase and intensity. In photonic systems, an acoustic wave propagating ...

Active metadevices integrated with semiconductors. (a) Hybrid silicon-metallic resonators for all-optical ultrafast active metamaterials. (b) Broadband metamaterial frequency switch with femtosecond ...

Modern oscilloscopes capture, view, measure, and analyze complex RF signals in the time, frequency, and modulation domains. Time-domain analysis, the original oscilloscope function, allows users to ...
