Abstract

We have developed a novel near-field microwave probe system which is able to simultaneously excite and readout the oscillation of a range of mechanical resonators, ranging in size from sub-micron to hundreds of microns. In this paper we discuss the coupling strength between a near-field microwave coaxial probe and a conducting cantilever. We present experimental results on a variety of excitation and readout methods, including a novel self-sustaining microwave interrogated oscillator with excellent frequency stability. We describe a parametric technique for driving NEMS resonators in a low-noise manner and reading them out using different excitation techniques. Finally we present designs for a scanned array system which allows a single microwave source to interrogate a range of membrane resonators. This has potential for biosensor and other future applications.
