1. Classical analog of electromagnetically induced transparency for slow light A classical effect of electromagnetically induced transparency (EIT) is demonstrated in a planar metamaterials in the ultraviolet regime. The EIT unit cell consists of a vertical cut wire as the bright resonator and two horizontal cut wire pairs as the dark element. The destructive interference between the two resona...

We present a theoretical and experimental study of a bilayered metamaterial structure for subwavelength imaging of magnetic field. The simplest version of such a structure consists of one or two linear arrays of capacitively loaded split pipe resonators. Its subwavelength physics is governed by strongly anisotropic magnetic coupling between individual resonators and by propagation of magnetoind...

Broadband perfect metamaterial absorbers have been drawing significant attention in recent years. A close-to-unity absorption over a broad spectral range is established and this facilitates many photonic applications. A more challenging goal is to construct a broadband absorber with a tailored spectral absorption. The spectral absorption control and spectral shaping are very critical in many ap...

---This paper proposes a technique which improves Directivity and control of Beam-Steering by including metamaterial surfaces onto microstrip patch antenna superstrate used for wireless communication applications. Metamaterials are designed with Artificial Magnetic Conductor (AMC), inductive and capacitive planar structures. These structures allow obtaining Partially Reflective Surfaces (PRS). ...

Kirigami is the art of paper cutting, and it emerging as an elegant design manufacturing solution in mechanical metamaterials. Currently, majority kirigami designs focus on shape-morphing, but there little attention remarkable properties they can produce: high strength to weight ratio where bear thousands times their own weight. This proposes a kirigami-based, strong, yet lightweight metamateri...
