The physics and applications of a broad class of artificial electromagnetic materials composed of lattices of aligned metal rods embedded in a dielectric matrix are reviewed …
Electromagnetic metamaterials (MMs) and metasurfaces (MSs) are artificial media and surfaces with subwavelength separations of meta-atoms designed for anomalous …
Utilizing a microwave setup, we experimentally verify our recently developed theory of energy squeezing and tunneling [Phys. Rev. Lett. 97, 157403 (2006) PRLTAO 0031-9007 …

The exotic wave interaction of metamaterials has been recently applied to various cloaking applications, but the metamaterial realization in practical cloaks is still far from ideal. Current …
The ability to render objects invisible using a cloak (such that they are not detectable by an external observer) has long been a tantalizing goal,,,,,. Here, we demonstrate a cloak …
The development of metamaterials, ie, artificially structured materials that interact with waves in unconventional ways, has revolutionized our ability to manipulate the propagation of …

We explore in detail the concept of mantle cloaking, showing that a single, ultrathin, conformal metasurface may drastically suppress the scattering from planar [one-dimensional …

We derive from first principles an accurate homogenized description of periodic metamaterials made of magnetodielectric inclusions, highlighting and overcoming relevant …
Plasmonic cloaking is a scattering-cancellation technique based on the local negative polarizability of metamaterials. Here we report its first experimental realization and …
