Prospects of Huygens' Metasurfaces for Antenna Applications
文献摘要：
1. Introduction
In recent years, there has been an intense research effort by the international community in the field of''artificial"electromagnetic materials, or''metamaterials."Metamaterials are engineered struc-tures that induce a tailored arrangement of magnetic and electric dipole moments when excited by an incident electromagnetic field. Under certain conditions, such as when the comprising unit cells are sub-wavelength, metamaterials can be homogenized and described in terms of macroscopic constitutive parameters such as permeability, permittivity, and refractive index. A sum-mary of the early work on ''artificial dielectrics"can be found in Ref. [1]. In the over 20-year-old field of metamaterials, the desired macroscopic parameters correspond to extreme properties such as negative permittivity, negative permeability, and a negative refrac-tive index. Perhaps the most recognized metamaterial is that which realizes a negative refractive index, originally demonstrated at microwaves and based on a unit cell made out of a split-ring reso-nator and a wire [2]. In the engineering community, a transmis-sion-line approach was developed for implementing metamaterials with significant advantages, such as reduced trans-mission losses and wider operating bandwidths [3,4].
