Invisibility cloak without singularity
An elliptical invisible cloak is proposed using a coordinate transformation in the ellipticalcylindrical coordinate system, which crushes the cloaked object to a line segment instead of a point. The elliptical cloak is reduced to a nearly-circular cloak if the elliptical focus becomes very small. The advantage of the proposed invisibility cloak is that none of the parameters is singular and the...
متن کاملOptical Cloak of Invisibility
We present the design and analysis of an optical cloak of invisibility with non-magnetic metamaterials. The general recipe for the implementation of such a device is provided. The cloaking performance is illustrated with finite-element simulations. ©2007 Optical Society of America OCIS codes: (230.3990) Microstructure devices; (160.4760) Optical properties; (999.9999) Meta-materials
متن کاملElectrostatic Field Invisibility Cloak.
The invisibility cloak has been drawing much attention due to its new concept for manipulating many physical fields, from oscillating wave fields (electromagnetic, acoustic and elastic) to static magnetic fields, dc electric fields, and diffusive fields. Here, an electrostatic field invisibility cloak has been theoretically investigated and experimentally demonstrated to perfectly hide two dime...
متن کاملUnveiling malaria’s “cloak of invisibility”
446 Virulence Volume 3 Issue 5 Recent studies have identified cytoskeletal elements in bacteria which play important roles in cellular morphology, cell division, DNA segregation and the establishment of cell polarity. However, our understanding of the contribution the bacterial cytoskeleton makes toward virulence is lacking. The MreB protein is a bacterial homolog of eukaryotic actin and intera...
متن کاملMacroscopic invisibility cloak for visible light.
Invisibility cloaks, a subject that usually occurs in science fiction and myths, have attracted wide interest recently because of their possible realization. The biggest challenge to true invisibility is known to be the cloaking of a macroscopic object in the broad range of wavelengths visible to the human eye. Here we experimentally solve this problem by incorporating the principle of transfor...
