Abstract:The paper overviews our recent work on the synthesis of metasurfaces and related concepts and applications. The synthesis is based on generalized sheet transition conditions (GSTCs) with a bianisotropic surface susceptibility tensor model of the metasurface structure. We first place metasurfaces in a proper historical context and describe the GSTC technique with some fundamental susceptibility tensor considerations. On this basis, we next provide an in-depth development of our susceptibility-GSTC synthesis technique. Finally, we present five recent metasurface concepts and applications, which cover the topics of birefringent transformations, bianisotropic refraction, light emission enhancement, remote spatial processing, and nonlinear second-harmonic generation.

“…The geometry of the devised circular polarization converter illustrated in Figure A uses bisected ring structures for wide transmission bandwidth from 24.0 to 40.0 GHz. Asymmetric vertical and horizontal gaps along with the metallic strip pattern in the bottom face is devised to create the desired phased difference between the Transverse Electric; Vertical polarization (TE) and Transverse Magnetic; Horizontal polarization (TM) modes.…”

This letter entails a methodology to steer circularly polarized (CP) wave main beam in the near‐field region. The letter first demonstrates a planar circular polarizer which can convert an incoming linearly polarized wave into a CP wave from 24.0 to 40.0 GHz. Afterwards a one‐dimensional Fresnel zone plate consisting of electrically opaque and transparent regions is devised to formulate constructive interference for CP near‐field beamsteering at 22°. Measurement ascertains that the axial ratio and TE/TM phase difference at the aforementioned angle is 0.36 dB and 87.1°.

“…For instance, cross polarization converters have been designed by the anisotropic high impedance surfaces which could cause different phase delays for different polarization waves [8], [9]. Furthermore, by controlling the amplitude and phase delay of reflected or transmitted orthogonally polarized wave, the circular polarizers are proposed [10][11][12][13][14][15]. Chiral metamaterials have also been utilized to manipulate the polarization and obtain asymmetric transmission [16][17][18][19].…”
