“…Furthermore, the obtained measurements result correspond closely with the simulated outcomes. The scattering wave, wave deflection, measurement errors, small size of the manufactured absorber, test cable, the soldering of resistors, disparity between simulation and measurement environments may all contribute to this variance in the absorptivity curve Sambhav et al ( 2021) Bilal et al (2021)Jha et al (2022.…”

In this paper, we have explored a compact wideband metamaterial absorber unit-cell structure comprises four square-shaped conducting patches of copper and connected with four lumped resistors supported by FR-4 as a substate material which followed by conducting ground plain in the microwave (4 GHz to 15GHz) regime of the spectrum. The proposed structure has been analysed and simulated using CST Studio Suite a commercial simulated based on finite integration techniques to yield several performance metrics for comprehensive understanding of broad-spectrum absorbers. The proposed wideband metamaterial absorber is polarization insensitive due to its symmetric structure under a normal incident angle and has potential applications for the radar cross-section (RCS) reduction, target stealth, and electromagnetic wave protection. Further, the proposed structure has been fabricated and tested experimentally, and the achieved results are comparable with that of the simulation results.

Radar absorption structures made of an active frequency selective surfaces (AFSS) have enormous potential in the aviation, naval, and other industries. In this research paper, a systematic review (SR) is carried out in the field of the AFSS to bring uncertainties, obstacles, challenges, classifications, applications, and design issues that arrive in the development of the sub-6 GHz architecture. To bias the AFSS component, as per the signal requirements, a unique set of circuits (PIN diode) is required, with ON and OFF state and a transmission zone. The bandwidth of which is determined by the bias voltage supplied. It can behave as a complicated hybrid impedance structure by providing ON and OFF biasing voltage to a PIN diode embodied in an FSS structure. Higher manufacturing costs of AFSS components, more significant complexities involved, a large amount of power consumption, and reactive impedance losses are some common limitations faced while implementing and designing an AFSS. Many envisioned problems are corrected with the AFSS design, current or creative implementations, and processing parameters are investigated progressively. It implies that new AFSSs will be an alternative to regular FSSs in the future. This paper is based on Kitchenham’s three-phase review procedure and supplements it with results, views, and recommendations from other leading experts in the field.
