Pneumatically switchable graded index metamaterial lens

Khodasevych, I. E.; Shadrivov, I. V.; Powell, D. A.; Rowe, W. S. T.; Mitchell, A.

Description

A low-profile pneumatically switchable graded index metamaterial lens operating at 9 GHz is proposed and practically demonstrated. An effective graded refractive index is engineered using an array of electric resonators of differing resonant frequency. Normal orientation of the resonators allows ultrathin single metamaterial layer lens design. Switching between focusing and non-focusing states is practically demonstrated by shorting the gaps in split ring resonators and eliminating the resonant...[Show more]
