Abstract
Based on the multisplitring resonator MSRR with MEMS switches a tunable metamaterial component is proposed in this paper to realize multiband applications Numerical simulations are carried out to verify the tunable capacity of the proposed structure The simulated results show that the resonance frequency of the metamaterial component shifts to higher frequencies when the MEMS switches are at different states and depends strongly on the place state and microbeam height of MEMS switches Moreover the large tunable range can be obtained by controlling the up state or down state of MEMS switches while the small tunable range can be obtained by controlling microbeam height of MEMS switches That is such controlling ways can realize both rough and minor tunable metamaterial component The tunable method proposed in this paper is of great practical values in designing tunable metamaterial and negative refractive index materialThe work described in this paper was supported by the China Postdoctoral Science Foundation 20090450226 Research Foundation of Education Bureau of Heilongjiang Province 2010 and Youth Foundation of Harbin University of Science and Technology 2009YF024
