Abstract:	This work describes progress toward designing and modeling reconfigurable band-pass filters based on RF microelectromechanical systems (RF-MEMS) metamaterials. A device consisting of a coplanar waveguide structure that combines complementary split ring resonators (CSRRs) and RF-MEMS varactor bridges, operating at K and Ka-band, is proposed. Several layouts have been designed and electromagnetically (EM) simulated. A full equivalent-circuit model for the description of the proposed structure, including transmission lines, RF-MEMS, subwavelength resonators and coupling parameters, is provided. A high degree of accuracy between EM simulations behavior and electrical model has been obtained.
