Title:Invisibility Cloaks for Asymmetric Objects
Seminar:CCMA Luncheon Seminar
Speaker:Gregor Kovacic, Rensselaer Polytechnic Institute
Abstract:
A composite metametrial with appropriately chosen electro-magnetic material properties can be used to create an "invisibility cloak" around an object. This is a layer of metamaterial which takes a set of light rays of a specific color that impinge on the object and guides them around this object to emerge at appropriate points on the opposite side of the object as if the rays were straight all along. Breakthrough works by physicists used ray tracing to compute "invisibility cloaks" in the forms ofspherical and cylindrical shells, and actually manufactured a cylindrical "invisibility cloak" that operates in the microwave regime. We used Hamiltonian ray tracing to compute rays passing through "invisibility cloaks" of more general shapes, including triaxial ellipsoids, cones, and objects composed of parts of cones, cylinders, and spheres. This talk will present the results of our work.
