Jean-Michel Le Floch,Yaohui Fan,Michel Aubourg,Dominique Cros,N. C. Carvalho,Qingxiao Shan,Jeremy Bourhill,Eugene Ivanov,Georges Humbert,Valérie Madrangeas,Michael E. Tobar +10 more
TL;DR: This work designs a highly tunable cavity that can be tuned from 2 GHz to 22 GHz just by inserting a post into a fixed dimensioned cylindrical cavity, and shows this is possible, as the mode structure transforms from a re-entrant mode during the tuning process to a standard cylINDrical transverse magnetic mode.

TL;DR: In this paper, the interaction of Whispering Gallery Modes (WGMs) with dilute spin ensembles in solids is an interesting paradigm of Hybrid Quantum Systems potentially beneficial for Quantum Signal Processing applications.
Journal ArticleDOI
Piezoelectric voltage coupled reentrant cavity resonator
TL;DR: It is shown that a piezoelectric voltage coupled microwave reentrant cavity can be implemented as a voltage tunable resonator, a transducer for exciting and measuring mechanical modes of the structure, and a transducers for measuring comparative sensitivity of the piezOElectric material.
