“…The values of the extracted parameters are shown in Figure 27. At peak frequencies of 7.8 and 16.7 GHz, the real and imaginary components of the extracted permittivity, and permeability obtained are almost equal, resultinginimpedancematchingoftheMSwithfree space, which minimizes the co-polarization reflection and maximizes the absorption [63].…”

Metamaterials are efficiently homogenizable arrangements of artificial structural components engineered to achieve beneficial and exotic electromagnetic (EM) properties not found in natural materials. Metasurfaces are the two-dimensional analogue of metamaterials consisting of single-layer or multi-layer stacks of planar structures. Both metamaterials and metasurfaces have great potential to be used in a wide range of applications, e.g., antennas, polarization converters, radar cross section (RCS) reduction, and absorbers, to control the amplitude, phase and polarization of the reflected and transmitted EM waves. This chapter presents a brief overview of the known types and applications of metamaterials/metasurface followed by comprehensive analysis of these surfaces for antennas performance enhancement, polarization conversion, RCS reduction, and wave absorption.

“…A metasurface prototype is designed which cover 10.5-16.2 GHz, which works not only for normal incidences but also for oblique incident angles. 33 However these MSs have incident angles dependent responses, complex designs or non-standard thicknesses, which limits their practical applicability. Attaining a broadband, incident angle independent response through a thin MS is the common challenging task of research community.…”

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.

Polarization converters play an important role in practical applications to manipulate the electromagnetic wave. However, the development of a polarization converter that possesses both high conversion efficiency and a wide frequency band is very challenging due to the trade-off between them. Here, we present an ultra-wideband and high-efficiency cross-polarization converter based on a double split ring shaped metasurface. The performance of the proposed converter is simulated and verified by experiments, showing a good agreement. The proposed polarization converter shows the cross-polarization conversion with a conversion efficiency above 93% in a wide frequency range from 4.0 to 14.0 GHz covering the entire C- and X-bands and a part of the Ku-band due to the combination of multi-modes of magnetic and electric resonances. Compared with other ultra-wideband polarization converters, the proposed converter shows excellent characteristics in terms of high efficiency, wide frequency band, and lightweight design, demonstrating a great potential application in C-, X-, and Ku-bands.
