The design, fabrication and measurement of a recon-g-urable -shnet metamaterial based on a new method of tuning by chang-ing unit cell geometry is reported. Retractable elements are added to the unit cell utilizing pneumatically actuated switching. It is shown that the pneumatic actuation approach can unite a number of metallic elements into a complex conducting structure. Experimental demon-stration con-rms that the structure operates at two di®erent frequen-cies in the GHz range in distinct actuation states. The measured results also show good agreement with numerical simulations.
