According to modern oceanographic perspectives that emphasize microbial pathways, phagotrophic protists
comprise one to several levels of intermediate consumers between phytoplankton and larger metaz...
For a general complex scattering potential defined on a real line, we show that the equations governing invisibility of the potential are invariant under the combined action of parity and time-reversa...
Experimental demonstration of a broadband array of invisibility cloaks in the visible frequency range

Physicists in the UK have proposed a "space–time" invisibility cloak that, if built, could be used to prevent signal interference or give the illusion of a Star Trek teleportation device. The idea com...
Two dimensional invisibility cloaking for Helmholtz equation and non-local boundary conditions

Transformation optics constructions have allowed the design of cloaking devices that steer electromagnetic, acoustic and quantum waves around a region without penetrating it, so that this region is hi...
Invisibility in billiards
Billiards shape optimization problems of minimal resistance classical scattering Newtonian aerodynamics invisible bodies
2010/11/30
The question of invisibility for bodies with mirror surface is studied in the frame-work of geometrical optics. We construct bodies that are invisible/have zero resis-tance in two mutually orthogonal ...
