Abstract

With the deformation theory of continuum mechanics, we extend the coordinate transformation method to design arbitrary transformation metamaterials, which are inherently transparent for electromagnetic waves. In the experiment, the metamaterial capable of bending waves is verified. The transparency phenomenon based on the field cancellation effect is also discussed. The composites fabricated with Carbon nanotubes and rubbers are demonstrated experimentally to have the cloaking effect for metal cylinders.
