High figure of merit cylinder?shaped negative refractive index metamaterial based on paper as dielectric material

The design of unit cell metamaterial can tailor the permittivity and permeability. negative refractive index was achieved while real part permeability simultaneously or ? r ? i + < 0 conditions were satisfied, where , are permittivity, imaginary permeability, respectively. Currently, based on paper is a fascinating issue. Additional, used as dielectric due to its eco-friendly spacer. critical rule for achieving high figure merit (FoM) index. This work aims FoM cylinder-shaped material. structure simulated by CST microwave studio. electromagnetic properties estimated from scattering parameter (S-parameter) result. yields performance. generated at 3.4–3.91 GHz. above condition satisfied 3.5–3.91
