Cloak/anti-cloak interactions.
Coordinate-transformation cloaking is based on the design of a metamaterial shell made of an anisotropic, spatially inhomogeneous "transformation medium" that allows rerouting the impinging wave around a given region of space. In its original version, it is generally believed that, in the ideal limit, the radiation cannot penetrate the cloaking shell (from outside to inside, and viceversa). How...
متن کاملElectromagnetic wave interactions with a metamaterial cloak.
We establish analytically the interactions of electromagnetic wave with a general class of spherical cloaks based on a full wave Mie scattering model. We show that for an ideal cloak the total scattering cross section is absolutely zero, but for a cloak with a specific type of loss, only the backscattering is exactly zero, which indicates the cloak can still be rendered invisible with a monosta...
متن کاملCompact-sized and broadband carpet cloak and free-space cloak.
Recently, invisible cloaks have attracted much attention due to their exciting property of invisibility, which are based on a solid theory of transformation optics and quasi-conformal mapping. Two kinds of cloaks have been proposed: free-space cloaks, which can render objects in free space invisible to incident radiation, and carpet cloaks (or ground-plane cloaks), which can hide objects under ...
متن کاملDC magnetic cloak.
DOI: 10.1002/adma.201104012 Isolation from external magnetic fields is a fundamental requirement that appears in various scientific experiments today. In particular, for applications where static or slowly varying magnetic fields need to be screened, enclosures made of superconductors or high magnetic permeability metal alloys are typically utilized. These are called “shields” as they isolate t...
متن کاملCloak-and-dagger publishing.
71 SPECIALSECTION could escape from a lab and cause a human pandemic, or that revealing details about the research could inadvertently aid terrorists seeking a bioweapon. They asked the National Science Advisory Board for Biosecurity, set up after the 2001 anthrax attacks, to review the H5N1 studies. It initially recommended that the papers be published only if journal editors deleted key metho...
