General complementary media: electromagnetically transforming a small rectangle object to a large convex/concave pentagon object
Based on the complementary media theory, we propose a way to transform a small object into a large one by coating it with a metamaterial shell with negative refractive index. Small waveguides made with this structure can replace large virtual tunnels to connect two separated waveguides. A small portal coating with complementary media is also designed in which a large entrance is concealed from electromagnetic wave detection. Two-dimensional numerical simulations are performed to illustrate the designed devices.
