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 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 کاملThe Schistosome Egg in Transit
The Schistosoma mansoni egg develops in the female worm ooctype where the oocyte and surrounding vitelline granules become enclosed by a protective shell. The schisto some egg is then transported through the uterus to emerge from the genital pore of the intravascular worm. It is not known how eggs successfully enter the perivascular space and how they transit the intestinal wall into the stools...
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...
