Frequency-multiplexed tunable logic device based on terahertz graphene-integrated metamaterial composed of two circular ring resonator array

Abstract This paper presents a novel terahertz (THz) graphene-based tunable metamaterial that operates as a frequency-multiplexed logic device. The structure consists of a gold layer, a dielectric substrate, and an array of graphene resonators formed by two circular ring resonators per unit cell. Th...
