FDTD Modeling of a Cloak with a Nondiagonal Permittivity Tensor
Figure 3
FDTD results for the elliptic-cylindrical cloak. (a) field distributions using 10 nm (black lines are inside and outside shells of the cloak). (b) Radar cross section (RCS) scattered by a PEC (without cloak) and cloak using different grid spacings, 20, 10, and 5 nm (radial coordinate is dB).
