Title: Fluid interactions with metafilm/metasurfaces for tuning, sensing, and microwave assisted chemical processes
Published: May 25, 2011
Abstract: In this paper we demonstrate tunability of a metafilm, which is the two-dimensional equivalent of a metamaterial, also referred to as a metasurface, by changing the permittivity in a micro-fluidic channel that interacts with the metafilm. Numerical simulations and experimental results are presented for a metafilm consisting of metallic electric-coupled OE2 resonators operating in S-band near 3.6 GHz. The localization and enhancement of the electric field in the metafilm which interacts with the fluid channels is explored as a means for implanting and aiding microwave assisted chemical processes. Applications of such micro-fluid tunable metafilms are discussed.
