Split-ring resonators are excellent left-handed metamaterials for significant electromagnetic coupling behavior. In this work, a split-ring resonator prepared with Ni-doped zeolitic imidazolate framework-67/epoxy resin (ZIF-67/ER) was embedded in the top layer to optimize microwave absorption efficiency 2–4 GHz frequency band. The ZIF-67/epoxy served as bottom improve 4–8 Honeycomb conductive c...

This study proposes a 2.45-GHz double split-ring resonator for measuring the dielectric constant in both solids and liquids. Two concentric rectangular rings with asymmetric splits are used proposed to achieve high-quality factor increasing sensitivity resonant frequency changes. The constants of liquids obtained based on quadratic polynomial equations different coefficients, by shift reference...

Abstract A terahertz broadband polarization converter based on the metasurface of a double-split ring resonator is proposed. The structural parameters this device have been optimized in numerical simulations. results show that frequency range from 0.49 to 1.88 THz (bandwidth 1.39 THz) proposed rotates incident linearly polarized waves through 90°. conversion rate more than 80%. coefficient refl...
