RF and Surface Properties of Bulk Niobium and Niobium Film Samples
, 2012 The surface resistance Rs of superconducting cavities can be obtained from the unloaded quality factor Q0. Since RS varies strongly over the cavity surface its value must be interpreted as averaged over the whole cavity surface.

Extraction of lateral eigenmode properties in thin film bulk acoustic wave resonator from interferometric measurements [PDF]
, 2010 A heterodyne laser interferometer is used to study acoustic wave fields excited in a 1.8 GHz AlN thin film bulk acoustic waveresonator. The electrical response of the resonator exhibits a strong thickness resonance onto which spurious modes, caused by ...
