Coordinate systems for the eccentric elliptic annular cloak. (a) The system and the associated unit vectors. The solid (blue) and dashed (green) curves represent constant and contours, respectively. (b) The system after transformation and the unit vectors. The region shown shaded in gray is completely excluded from the system.
Snapshots of the total magnetic field for two-dimensional TM mode scattering from an elliptic PEC cylinder. (a) PEC cylinder exposed directly to the incoming plane wave propagating in the direction. (b) The same cylinder surrounded by the eccentric elliptic annular cloak. (c) The cloaked cylinder subject to the illumination by a plane wave making an angle of from the direction.
Cloak material parameters on the outer boundary of the cloak shown in Fig. 2 in terms of an orthogonal set of unit vectors , , and .
