Abstract

Searching higher frequency regions for axion dark matter using microwave cavity detectors requires smaller size cavities as the resonant frequencies scale inversely with cavity radius. One of the intuitive ways to make an efficient use of a given magnet volume is to bundle an array of cavities together and combine their individual outputs ensuring phase-matching of the coherent axion signal. In this article, an extensive study of realistic design for the phase-matching mechanism of multiple-cavity systems is performed and its experimental feasibility is demonstrated using a double-cavity system.
