Abstract

This paper presents a comparative study between different slotted anisotropic meta unit-cell having various polygon architectures to extract the variation of surface impedance (Z_surf) based on the structural parameters. A systematic way for extracting the Z_surf using the transverse resonance method is proposed A closed-form mathematical relationship has been established to make a non-linear mapping between Z_surf and each parametric variation of the different polygon-shaped unit cells.
