In this paper, off-axis characteristic of subwavelength focusing in anisotropic metamaterials is examined and analyzed numerically. Conditions for reducing aberrations of off-axis focus are presented and demonstrated. Also discussed are geometrical parameters’ influences on the off-axis focusing behavior.
