In the past twenty years,electromagnetic metamaterials represented by left-handed metamaterials (LHMs) have attracted considerable attention due to the unique properties such as negative refraction,perfect lens,and electromagnetic cloaks.In this paper,we present a comprehensive review of our group’s work on metamaterials and metasurfaces.We present several types of LHMs and chiral metamaterials.As a two-dimensional equivalent of bulk three-dimensional metamaterials,metasurfaces have led to a myriad of devices due to the advantages of lower profile,lower losses,and simpler to fabricate than bulk three-dimensional metamaterials.We demonstrate the novel microwave metadevices based on metamaterials and metasurfaces:perfect absorbers and microwave patch antennas,including novel transmission line antennas,high gain resonant cavity antennas,wide scanning phased array antennas,and circularly polarized antennas.
