Electric field (𝐸_𝑧) distributions in the computational domain. (a) Scattering pattern of the object with anisotropic permeability (𝜇_𝑟𝑜=−1,𝜇_𝜑𝑜=2). The plane wave is incident at an angle of 45°. (b) The object in (a) is hidden by the reciprocal cloak. (c) Scattering pattern of an object with linearly changing permittivity (𝜀_𝑧𝑜=2𝑟+3). The current source with amplitude of 10⁻³A is located at (−0.3 m, −0.25 m). (d) The object in (c) is hidden by the reciprocal cloak.
