Spacial Energy Distribution Manipulation with Multi-focus Huygens Metamirror

Abstract Huygens metasurface is a planar array of crossed electric and magnetic dipoles, which provide specific surface current to tailor the electromagnetic field distribution. By changing the geometrical parameters of the proposed unit cell, the manipulation range of reflection phase can achieve 2...
