Microwave optomechanical device

Microwave optomechanical circuit, composed of LC microwave resonator capacitively coupled with a nano-mechanical oscillator, allows to probe, detect and manipulate mechanical phonons through microwave photons. Such a kind of device can serve for quantum engineering and classical sensors.
