“…For development of 5G communication systems, it is necessary to solve many problems related to electromagnetic compatibility and develop materials effectively absorbing electromagnetic radiation at high frequencies. Many researchers worldwide concentrate on the design of absorbers for various frequency ranges [1][2][3][4][5][6][7][8][9].…”

Abstract-The general principles of design and development of microwave absorbing materials are discussed and analysed in respect to 26-37 GHz frequency range (Ka-band). Dispersive composite materials based on carbon nanotubes in epoxy resin matrix are produced, and their electromagnetic responses are investigated in Ka-band. Both theoretical and experimental results demonstrate that presented composites may be used as compact effective absorbers in 26-37 GHz range.

“…Simulation of the same model is done using HFSS. Authors concluded that reflection loss with double-layer absorber reached up to − 28.32 dB for normal incidence, whereas in case of oblique incidence, it is − 17 dB which means that incident angle greatly affects the reflection loss which is not desirable [66].…”

Advancement in the use of microwave electronics by the wireless devices, networks' server and switches, wireless antenna systems, and mobile phone base station potentially increased the radio-frequency interference. Effective elimination of this electromagnetic pollution is very necessary for proper working of electronic equipments. Microwave absorbers serve the above purpose leading to have enormous commercial and defence applications, for antenna shielding and laboratory testing of antenna. Researchers are, therefore, paying much attention on the study and fabrication of different materials and their shapes so as to use them as an absorber which ideally exhibits properties such as (1) strong absorption; (2) minimize the reflection of microwaves at air to absorber interface; (3) broader bandwidth; (4) low weight and thickness; (5) ignition at very high temperature; (6) frequency tunability; and (7) transparent and cost effective. In this paper, absorber designs based on materials and geometries proposed by number of researchers have been extensively reviewed. The preamble presented here can be explored to design novel absorbers combining material and geometry-based designs for enhanced performance to meet the future challenges.

“…The problem of an electromagnetic multilayer dielectric design optimization for a frequency band and a desired range of incident angles has been introduced in recent years using such metaheuristic optimization algorithms as the genetic algorithm [1,2], particle swarm optimization (PSO) [3,4], or a hybrid algorithm that combines ant colony optimization (ACO) with the microgenetic algorithm [5]. In this study, an effective algorithm presented by Socha and Dorigo [6] in 2008 called ant colony optimization for a continuous domain (ACO R ) is applied to design a C-sandwich radome [7] with an applicable range of incident angle (0°-70°) in both the transverse electric (TE) and transverse magnetic (TM) modes for the X-and Kubands.…”

In this study, an effective method for designing an electromagnetic multilayer radome is introduced. This method is achieved by using ant colony optimization for a continuous domain in the transmission coefficient maximization with stability for a wide angle of incidence in both perpendicular and parallel polarizations in specific X-and Ku-bands. To obtain the optimized parameter for a C-sandwich radome, particle swarm optimization algorithm is operated to give a clear comparison on the effectiveness of ant colony optimization for a continuous domain. The qualification of an optimized multilayer radome is also compared with an effective solid radome type in transmitted power stability and presented in this research.
