“…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.

“…An RL value exceeding -10 dB is obtained in the frequency range of 8-15 GHz and a thickness of 1.5-3.0 mm. The experimental results show that the optimum thickness of CF@Fe composites is approximately 2.0 mm, thinner than that reported in other studies [14,15]. CFs are known to be favorable microwave absorbing materials [12,13].…”

“…However, CFs is a resistive loss material with no magnetic property and has poor absorption property when used alone. Extensive studies have been carried out to develop high performance microwave absorbing materials by use the advantage of magnetic materials and carbon fibers materials, such as Ni/CFs and Fe 3 O 4 /CFs [14][15][16]. The combining carbonyl iron and CFs has been extensively reported, While the way is simply mixed two kind of materials.…”

The current paper discusses the preparation of novel Fe-coated carbon fiber (CF@Fe) composites using metal organic chemical vapor deposition (MOCVD) for use as microwave absorbing materials. SEM, EDS, and XRD studies show that the MOCVD method can produce a uniform coating of iron on the CFs. Compared with common CF, the CF@Fe composites have higher resistivity and magnetic loss, which gradually increase with increasing iron content. At an CF@Fe weight fraction of 8 %, the minimum reflection loss (RL) is -38 dB at 13.4 GHz and a corresponding thickness of 2.5 mm. An RL exceeding -10 dB is obtained in the frequency range of 8-15 GHz and a thickness of 1.5-3.0 mm. The results indicate that the prepared composite has excellent electromagnetic absorption properties with lightness.

“…Of particular relevance is the development of the future generation communication systems, in which the questions of electromagnetic compatibility alongside the environmental protection will have to be addressed. There is a worldwide activity in this sector, and the search for new broadband absorbing materials is ongoing constantly [1][2][3][4][5][6]. The role of ferromagnetic resonance [7][8][9], Ohmic losses [10][11][12], dipole relaxation [13] and lossy scattering on the periodic structure of metamaterials [14] are some of the currently pursued questions.…”

Abstract-We report the modelling and characterization of microwave absorbing materials specially designed for 26-37 GHz frequency range (Ka-band).Composite materials based on carbon nanotubes/BaTiO 3 /Fe 3 O 4 in a phosphate ceramic matrix were produced, and their electromagnetic response was investigated. Both theoretical and experimental results demonstrate that this material can absorb up to 100% of the power of an incident plane wave at a normal incidence angle. The physics underlying such absorption level is discussed in terms of refractive index of the material.
