چکیده
A simple scheme for the realization of terahertz (THz) fundamental-mode tunable closed-stopband composite right/left-handed leaky-wave antennas (CRLH LWAs) is presented. The proposed CRLH LWAs are reconstructed by graphene-based coplanar waveguide (CPW) transmission line supercells. Their shunt inductances achieved narrow graphene strips two unit cell structures halved. designed and confirmed numerical simulations. They also exhibit frequency-scanning behaviors at THz with narrower bandwidth than that conventional CPW THz. Besides, strong characteristics achieve condition more effectively. Therefore, supercell could further improve performance beam-steering

Tunable Dielectric Resonator-Based Left-Handed Leaky Wave Antenna
Recently, left-handed (LH) metamaterials have been achieved by arranging an array of TE resonant dielectric resonators (DRs) in a cut-off parallel plate waveguide [1], [2]. Since negative permittivity is provided by the TE cut-off background, the DRs only need to generate the required negative permeability in order to realize a LH metamaterial. This configuration provides a more flexible choice...
متن کاملImproved Composite Right/left-handed Cell for Leaky-wave Antenna
An improved composite right/left-handed (CRLH) unit cell optimized for a leaky-wave (LW) antenna is presented. This CRLH cell consists of a series of one transmission line, an interdigital capacitor, another transmission line and a shunt shorted stub. Introducing the transmission lines, the parasitic self-resonances of the capacitor are shifted outside the operational band, the radiation range ...
متن کاملPlanar Leaky-Wave Antennas
Leaky-wave antennas use a traveling wave to radiate continuously along a radiating aperture in order to produce a focused beam of radiation. Planar leaky-wave antennas are particularly attractive since they use simple dielectric layers and/or metallic screens over a grounded substrate layer. A simple source such as a dipole or slot inside the substrate or on the ground plane excites the leaky w...

In this paper, a compact plasmonic metamaterial absorber for terahertz frequencies is proposed and simulated. The absorber is based on metamaterial graphene structures, and benefits from dynamically controllable properties of graphene. Through patterning graphene layers, plasmonic resonances are tailored to provide a dual band as well as an improved bandwidth absorption. Unit cell of the design...
متن کاملDouble-side Radiating Leaky-wave Antenna Based on Composite Right/left-handed Coplanar-waveguide
A double-side radiating leaky-wave antenna based on composite right/left-handed (CRLH) coplanar-waveguide (CPW) is proposed. Dispersion diagram of the unit cell is investigated, and balanced property is confirmed. Thus, the CRLH leaky-wave antenna can have backfire radiation due to the left-handed property of the CRLH structure and broadside radiation at the balancing frequency point. The measu...
