“…The study only analyzes its performance under normal incidence without considering oblique incidence. The MSs in [9] and [28] also have relatively small sizes, with the former maintaining a PCR of over 90% at incident angles from 0 to 30 • , but its relative bandwidth is only 22.2%, and its dielectric substrate material is expensive FR-4. The latter achieves only 80% PCR under oblique incidence.…”

In this paper, we propose a wideband linear polarizer that utilizes metamaterial and metasurface techniques to achieve highly efficient polarization conversion. The proposed polarizer achieves a polarization conversion ratio exceeding 90% at 12.0-16.0 GHz, as confirmed by both simulated and experimental results. The effects of geometric parameters, incidence angle, and polarization angle on the performance of the polarizer are analyzed, and it is demonstrated that the polarizer maintains an extremely high polarization conversion efficiency even under wide-angle incidence. The polarization conversion mechanism is elucidated through the examination of eigenmode and surface current distribution. This work holds significant promise for the control of electromagnetic waves, making it essential for upcoming engineering applications.

“…Hence the synthesis of compact, passive polarization-converting metasurfaces have become the solution to the above challenge. Only a few works have reported on multi-band passive polarization converting MS with compact size, high polarization conversion ratio (PCR) values, and high performance [ 24 , 25 , 26 , 27 , 28 , 29 , 30 ].…”

A compact and triple-band polarization converting reflective type metasurface (PCRM) with a high polarization conversion ratio (PCR) is proposed for strategic wireless antenna-integrated applications. The unit cell of the metasurface is composed of S- and G-shaped patches separated with a parasitic gap and the grounded via is connected to the full ground plane. The unit cell is etched on an FR4 substrate (dielectric constant, εr = 4.4, loss tangent, tan δ = 0.02), with compact dimensions of 10 mm3 × 10 mm3 × 1.6 mm3. This structure provides a resonance at 5.2 (ISM), 6.9, and 8.05 GHz (X-band) frequencies. The designed unit cell structure is studied for Transverse Electric (TE)/Transverse Magnetic (TM) incident waves and their responses to the various incident angles. The corresponding PCR is calculated, which shows 92% in the lower frequency band (5.2 GHz), 93% in the second frequency band (6.9 GHz), and 94% in the high-frequency band (8.05 GHz). The total efficiency of the structure shows 83.2%, 62.95%, and 64.6% at the respective resonance bands. A prototype of the proposed PCRM with 3 × 3 unit cells is fabricated to validate the simulated results. The experimental data agrees with the simulation results. The compactness, triple-band operation with a high PCR value of more than 92% makes use of the designed metasurface in wireless antenna-integrated applications at ISM and X-bands.

Summary A dual broadband cross‐polarization‐conversion (CPC) metasurface is designed, simulated, fabricated and results are experimentally verified. The designed patch of metasurface unit cell is composed of a triangular loop connected with two arcs at both ends. The metasurface is made of 44 × 44 unit cells arranged periodically on 1.6‐mm‐thick FR4 dielectric substrate, backed by a metallic copper sheet as a reflector surface on the back side of the dielectric substrate. The surface achieves CPC in two bands (7–8.5 GHz) and (13–19 GHz), in the microwave regime. The simulation results show that the polarization conversion ratio (PCR) is almost 90% for both x polarized (TM) and y polarized (TE) electromagnetic (EM) waves. The proposed metasurface is fabricated on 308 × 308 mm2 FR4 substrate plane. The simulated results are validated and are found in close covenant with the measured results.
