Ferroelectric based tuneable SRR based metamaterial for microwave applications

Özbay, Ekmel; Aydın, Koray; Bütün, Serkan; Kolodziejak, K.; Pawlak, D. (IEEE, 2007)

We discuss the possibility of achieving tunable split ring resonators at microwave frequencies. One method is to use varying capacitance values to tune the magnetic resonance frequency. As another method ferroelectric thin ...
Negative refraction and subwavelength focusing using left-handed composite metamaterials

Özbay, Ekmel; Aydın, Koray (SPIE, 2008-01)

We review experimental studies performed on left-handed metamaterials (LHM) at microwave frequencies. The metamaterial structure is composed of periodic arrays of split-ring resonators and wire meshes and exhibits a ...
