An inverse method of designing cylindrical cloaks without knowing coordinate transformation

摘要

An inverse way to define the parameters of ideal cylindrical cloaks isdeveloped, in which the interconnection between the parameters is revealed forthe first time without knowing a specific coordinate transformation. Therequired parameters are derived in terms of the integral form of cloakinggenerators, which is very general and allows us to examine the significance ofthe parametric profiles. The validity of such inverse way and the invisibilitycharacteristics are presented in full-wave numerical simulation of plane wavescattering by cloaked cylinders.
