The cloak material parameters are obtained from the spatial transformation approach. A near-ideal model of the invisibility cloak is set up to solve the boundary problem at the inner boundary in the cloak shell. The proposed design provides a more practical cloak geometry when compared to previous designs of elliptic cylindrical cloaks.8 pages, 1 figure, articleComputational PhysicsOpticsElliptic Cylindrical Invisibility Cloak, a Semianalytical Approach Using Mathieu Functionstext
