“…The second metric mentioned in Tables 1 and 3 is the simulated monostatic RCSR. The passive cancelation techniques used for RCSR are mostly simulated by two famous simulation softwares called Ansys‐high frequency structure simulator (HFSS) 44,58,60,62‐65,70,71,74,84,88,96,111,112,116,135 and CST Microwave Studio 22,25,54,62,75,103‐109,113,120,128,134,137,143,146‐148 . As all the approaches of Table 1 except 63 and some of the methods (checkerboard surfaces) of Table 3 are based on the phase cancelation technique achieved by phase difference of almost 180° ± 37°, a setup is utilized for full‐wave simulation of unit cells to determine the reflection coefficient characteristics such as phase and amplitude.…”

“…Recently, in Reference 12, Ji et al have used plasma and metamaterial as coating layers defined and analyzed by finite‐difference time‐domain (FDTD) method for RCSR of a cylinder. Similar to the shaping methods, coatings suffer from narrow RCSR bandwidth and high fabrication complexity. Using absorbent materials : absorbent materials (ie, radar absorbent material (RAM), 13‐22 microwave‐absorbing material (MAM), 21,23‐27 high impedance surface (HIS), 28‐30 and metamaterial absorber (MA)/ perfect metamaterial absorber (PMA) 31‐45 ) have been studied since 1950s 1 . These materials are lossy layers loaded on the target 46 which absorb the incoming EM energy and transform it into heat so that the backscattered EM wave to the radar receiver is decreased.…”

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.

A novel design for an ultra-wide bandwidth and thin microwave absorber is introduced utilizing two frequency selective surfaces (FSSs) with different patterns of resonating frequencies. The circuit parameters, inductance and capacitance, of the three types of FSS (square loop, cross, square patch) were determined using an equivalent circuit and strip wire conductor model. The square loop FSS indicates a low frequency resonance (10 GHz) due to its high inductance and capacitance. On the other hand, the square patch of small inductance reveals a high resonating frequency (36 GHz). By optimizing the combination of the two FSSs, an ultra-wide absorption bandwidth (6.3–40.0 GHz for −10 dB reflection loss) was designed with a small total thickness of 5.5 mm, which is close to the theoretical limit. The free space measurement result with a test sample prepared by the screen printing method was in good agreement with the simulation result and verified the validity of the proposed design method. For these periodic array structures, however, the grating lobes were observed above the high frequency limit, and it needs to be emphasized that the further control of the unit cell periodicity is important, particularly for large oblique incidence angles.
