Abstract: | By using coordinate transformation method, this paper obtains an
useful equation of designing meta-material cloaks embedded in
anisotropic medium. This equation is the generalization of what was
introduced early by Pendry et al (2006 \textit{Science}
{312 1780) and can be more widely used. As an example of its
applications, this paper deduces the material parameter equation for
cylinder cloaks embedded in anisotropic medium, and then offers the
numerical simulation. The results show that such a cylinder cloak
has perfect cloaking performance and therefore verifies the method
proposed in this paper. |
