Broadband electromagnetic metamaterials with reconfigurable fluid channels


Journal Article

We present the design, characterization, and experimental verification of broadband and tunable metamaterials based on reconfigurable fluid channels. We demonstrate through simulation that a finite-height cylinder of water in a background medium behaves as a nonresonant metamaterial. By changing liquid type or adjusting liquid level, we tune the effective material parameters of the metamaterial through altering the composition and amount of water used. We verify the efficacy of the metamaterial through experiment, demonstrating a design procedure for a metamaterial with broadband and tunable properties. © 2014 American Physical Society.
