Volume-preserving deformation of honeycomb wire media enables broad plasma-frequency tunability

Wire metamaterials are attractive for tunable resonators in dark-matter detection and electromagnetic technologies, but tuning the plasma frequency over a wide range remains challenging. This work employs a volume-preserving deformation of a honeycomb wire medium to realize over 60% plasma-frequency tuning, in both simulations and experiments. Introducing a quarter-wavelength air gap reproduces infinite-medium behavior within compact hexagonal cavities. These findings open the door to mechanically tunable, high-performance resonators for axion haloscopes and reconfigurable metamaterial devices.
