Motivated by the approximate cloaking problem, we consider a variable coefficient Helmholtz equation with a fixed wave number. We use finite element methods to discretize the equation. Numerical results are shown to exhibit cloaking behaviour. References A. Alu and N. Engheta. Achieving transparency with plasmonic and metamaterial coatings. Phys. Rev.
