“…However, it should be noted that the measured curves are unstable at the range of 8 GHz-12 GHz, which leads to the discontinuity of the 6 dB reduction bands for y-polarized incidence. This can be summarized as the fabrication errors, inaccurate angle between the sample and horn antennas, the experimental environment does not perfectly 5 satisfy the condition of ideal Compact Antenna Test Range (CATR) and so on. After repetitive measurements, the measured results are in reasonable agreement with the simulations.…”

“…On a broad scale, electromagnetic band gap [1] (EBG), high impedance surface (HIS) [2], frequency selective surface (FSS) [3], [4], polarization rotation surface (PRS) [5], [6], artificial magnetic conductor (AMC) [7][8][9][10], perfect absorbing material (PMA) [11][12][13][14] and spoof surface plasmon polaritons (SSPP) [15], [16] could be classified into the category of MS, among which AMC (easy processing and flexible in manipulating the reflection phase) and PMA (extremely low profile) draw increasingly interest of the researchers.…”

“…In the literature, Jiang et al [30] have shown that the polarisation states of light can be freely tuned by adjusting the structural parameters. In [31], a broadband metamaterial-based reflector has been introduced to convert LP incident waves to cross-polarised reflected waves or CP waves by adjusting dimensional parameters. In [32], a double-L-shaped structure has been proposed to obtain a multi-band multi-polarisation converter.…”

In this study, a dual‐broadband reflective polarisation converter with high efficiency for both linear‐to‐linear and linear‐to‐circular polarisations based on a metasurface is proposed. Owing to the characteristics of strong anisotropy and multi‐order plasmon resonances, the proposed polarisation converter can rotate an y/x polarised electromagnetic wave to its cross‐polarised (x/y) direction in the lower frequency band of 7.74–14.44 GHz (a fractional bandwidth of 60.4%) with over 0.9 polarisation conversion ratio. Besides, the proposed structure can also convert a linearly polarised incident wave to a circularly polarised one after reflection in the higher frequency band of 14.95–17.35 GHz (a fractional bandwidth of 14.9%). The performance in the two bands can be controlled separately by altering the proper parameters of the structure. Numerical analysis is used to predict the polarisation states of the proposed polarisation converter. Moreover, the physical mechanism of multiple resonances is discussed based on surface current distributions. A prototype of the polarisation converter is fabricated and measured. A reasonable agreement between the experiments and simulations is obtained. The design has a simple and scalable geometry, and is a good candidate for polarisation control devices in microwave, terahertz and optical frequency regions.

“…During past decades, metamaterials as artificial subwavelength periodic structures opened up a new avenue toward efficient manipulation of light due to their unique optical properties. The metamaterial can be valuable in optical rotation, negative refraction, invisible cloaking, polarization conversion, and beam control . Conventional polarization components are usually implemented using dielectric quarter‐wave plates to achieve phase accumulation .…”

A new approach to designing wideband wide-angle ultrathin linear-to-circular (LTC) polarization converter is presented. The metasurface is composed of a symmetric hexagonal structure formed by parallel metal slits printed on a grounded dielectric substrate, which has a pair of independent mutually perpendicular u and v axes, along AE45 directions with respect to the y-axis direction. Numerical simulation results show that the LTC metasurface can convert a linear polarization incidence wave into a circular polarization reflected wave. The bandwidth of axis ratio less than 3 dB is 2.24 THz, which is from 2.37 THz to 4.61 THz, and the fractional bandwidth is 64% under normal incidence. Meanwhile, the unit cell of the LTC metasurface is low profile (0.35λ 0 × 0.35λ 0 × 0.118λ 0 ) and compact. The polarization conversion efficiency can be maintained at over 85% at an angle of incidence up to 40 . Therefore, the proposed converter is useful for the development of the integrated THz polarization manipulation devices.
