摘要：

In this paper we demonstrate tunability of a metasurface, which is the two-dimensional equivalent of a metamaterial, also referred to as a metafilm, by changing the permittivity in a continuous flow channel that interacts with the metasurface. Numerical simulations and experimental results are presented for a metasurface consisting of metallic electric-field coupled resonators operating in S band near 3.6 GHz. The localization and enhancement of the electric field in the metasurface that interacts with the fluid channels is explored as a means for implementing and aiding microwave assisted chemical processes. Applications of such continuous flow tunable metasurfaces are discussed.
