Figure 3: FDTD results for the elliptic-cylindrical cloak. (a) 𝐻 𝑧 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).
