Mutual Conversion and Asymmetric Transmission of Linearly Polarized Waves Based on Metamaterial
نویسندگان
چکیده
In this paper, we propose a simple bilayered chiral matamaterial (CMM) consisting of two layers of split oval ring resonators by twisted angle of 90°. Numerical simulated results demonstrate that the proposed structure can realized a mutual polarization conversion and dual-band asymmetric transmission of linearly polarized waves in two opposite directions. The structure can convert the linearly polarized (LP) waves to its cross-polarized waves at 12.4 GHz and 14.6 GHz, respectively. The bandwidth of polarization conversion ratio (PCR) over 80% can be achieved from 12.5 to 17.7 GHz. Keywords—metamaterial; asymmetric transmission; dual-band; polarization conversion

An electrically thin chiral metamaterial structure composed of four U-shaped split ring resonator pairs is utilized in order to realize polarization rotation that is dependent on the polarization of the incident wave at 6.2 GHz. The structure is optimized such that a plane wave that is linearly polarized at an arbitrary angle is an eigenwave of the system at this frequency. The analytical relat...

Spatial k-dispersion design of SSPP modes in metamaterials is adopted to achieve high-efficiency transmission of electromagnetic waves through the metamaterial layer. By anisotropic design, the transmission phase accumulation in metamaterials can be independently modulated for x- and ...
