Abstract :
A controllable negative refraction device operated between 7 and 16 GHz is presented. This compact device, which is composed of split-ring resonators and metallic wires including pin diodes, presents a controllable permittivity and a fixed permeability. The switching of the electromagnetic state is demonstrated from transmission measurements between 7 and 16 GHz. The negative refraction of the material is verified from measurements at oblique incidence.
