A simple construction for a cylindrical cloak via inverse homogenization
Tom H. Anderson, Tom G. Mackay, Akhlesh Lakhtakia
An effective cylindrical cloak may be conceptualized as an assembly of adjacent local neighbourhoods, each of which is made from a homogenized composite material (HCM). The HCM is…
Ray trajectories for Alcubierre spacetime
Tom H. Anderson, Tom G. Mackay, Akhlesh Lakhtakia
The Alcubierre spacetime was simulated by means of a Tamm medium which is asymptotically identical to vacuum and has constitutive parameters which are ontinuous functions of the sp…
Ray trajectories for a spinning cosmic string and a manifestation of self-cloaking
Tom H. Anderson, Tom G. Mackay, Akhlesh Lakhtakia
A study of ray trajectories was undertaken for the Tamm medium which represents the spacetime of a cosmic spinning string, under the geometric-optics approximation. Our numerical s…
