Abstract:
An inverse way to define the parameters of cylindrical cloaks is developed, in which the cloaking parameters can be independently obtained without any knowledge of the corresponding coordinate transformation. The required parameters are derived in terms of the integral form of cloaking generators, which are very general and allow us to examine the significance of the parametric profiles. The validity of such inverse way and the invisibility characteristics are presented in full-wave numerical simulation of plane wave scattering by cloaked cylinders.

When a particle moves relative to an inertial frame, the equations of motion can be expressed using rectangular components. If the motion is confined to the x-y plane, the equations having the x and y coordinates only can be used to simplify the mathematical representation.
