“…Additionally, most of them have been performed only for monostatic RCSR at normal incident angle ignoring the wave polarization. Hence, nowadays, the modern passive techniques and structures based on phase cancelation or destructive interference using surfaces including frequency selective surface (FSS), 52‐55 EM band gap (EBG), 56‐59 artificial magnetic conductor (AMC), 47,48,60‐77 polarization rotation reflective surface (PRRS), 78‐95 metasurfaces, 96‐145 and hybrid methods, 146‐149 receive a lot of attention to improve the mentioned conventional techniques and overcome their limitations. In the recent decades, researchers have made a lot of efforts on these modern passive RCSR techniques and numerous works have been proposed and completed in order to achieve a system similar to the ideal RCSR system.…”

In this article, a comprehensive review of published techniques for reducing radar cross-section (RCS) of a target in various military and industrial applications is presented. This review contains the developments in this field over the last 24 years. In this comparative review, existing RCS reduction (RCSR) methods are categorized based on the type and the shape of their structures and their electromagnetic behavior and a variety of techniques of passive cancelation for RCSR is presented including the structures formed by both conductor and dielectric such as frequency selective surface, electromagnetic band gap, artificial magnetic conductor, different types of metasurfaces, polarization rotation reflective surface, and their combinations as hybrid techniques. A section is allocated for comparison in which a comprehensive comparison is drawn based on different characteristics of the structures, that is, the number and thickness of substrate layers, complexity and cost, RCSR bandwidth and level, their efficiency for TE and TM polarization, and their pros and cons. Moreover, the standard simulation and measurement setups and different kinds of optimization algorithms such as genetic algorithm, particle swarm optimization, and so on applied for RCS are presented and described. Finally, the conclusion, recommendations for future researches, and a trend of how the topic is possibly moving forward to overcome the main challenges are presented.

“…In addition to the AMC characteristics, the AR bandwidth can be extended with a MS that converts linear polarization (LP) to CP [5][6][7] in the off-band for 3-dB AR. Conversion techniques of polarization to cross polarization [8][9][10][11][12][13][14][15] and from LP to CP [16][17][18][19][20][21][22] have been extensively studied. For example, the principle of the structure in [9] to convert LP to the cross-polarization was explained based on a cut-wire resonator.…”

In this paper, a wideband metasurface reflector that converts plane wave polarization to cross polarization with a double-square-shaped unit cell is proposed, and the principle of polarization conversion based on polarization synthesis is presented. The proposed structure has a unit cell with a longest dimension of 0.37 wavelengths, a width of 0.23 wavelengths, and a thickness of about 0.09 wavelengths. Using this structure, 95% or more of the incident wave power is converted to cross polarization, covering a fractional bandwidth of 32.4% at 8.5 GHz.

“…Based on various MMs, many different polarization converters have been proposed , and they were usually realized in one of the following two methods: one is to divide a LP wave into two orthogonal components and generate a different phase between them (the fundamental of birefringence effect) by using anisotropic MMs, and the other is to mimic molecule chirality (the fundamental of optical activity) by using chiral MMs. The existing literature indicates that anisotropic two-dimensional MMs (also called metasurfaces) are more suitable for the design of reflective polarizers, and now a number of high-efficiency and ultra-wideband reflective linear polarizers were achieved by using multiple plasmon resonances of different anisotropic metasurfaces [4][5][6][7][8][9][10][11][12][13][14]. However, chiral MMs are convenient for designing transmissive polarizers.…”

In this work, a wide-angle and wide-band transmission-type circular polarizer based on a bi-layer anisotropic metasurface is proposed, in which the unit cell consists of two layers of identical patterned metal films deposited on the two sides of a homogeneous dielectric layer, and the geometric pattern of the metal film is a square aperture surrounding a concentric square-corner-truncated square patch. The simulated results show that the polarizer can realize a linear-to-circular polarization conversion at both x-and y-polarized incidences in the frequency range from 7.63 to 11.13 GHz with a relative bandwidth of 37.3%, and it can maintain a stable polarization conversion performance under large-range incidence angles. Moreover, it has no asymmetric transmission effect, and the transmission coefficients at x-and y-polarized incidences are completely equal. Finally, one experiment is carried out, and the simulated and measured results are almost in agreement with each other.
