Abstract / Description

It is theoretically shown that by cascading isotropic impedance sheets it is possible to obtain scattering performance as an idealized isotropic metasurface with electric, magnetic and magneto-electric surface parameters. ABCD matrices, scattering matrices, impedance matrices, and hybrid matrices are used to analyze the propagation of electromagnetic waves through layered media. It is also shown that metasurfaces can exhibit magnetoelectric coupling which is important for wide-angle impedance matching (WAIM) in phased-array antennas to reduce variation of reflection-coefficient with scan angle and polarization.
