“…The proposed RAMM thickness, bandwidth and operational bandwidth to thickness ratio indicated an outstanding performance towards overcoming the challenging task of having broadband and thin thickness absorber, compared to the currently published structures of its kind [27][28][29][30], [32], [34][35][36]. The below -10dB reflectivity bandwidth of 13.8 GHz for the designed RAMM is wider than the 10 GHz bandwidth obtained in [29], 13.2 GHz in [30] and 3.5 GHz in [32]. Others are 10 GHz [34], 3.13 GHz [35] and 3.18 GHz [36].…”

“…The results tend to be consistent in both shape and peaks, though there is deviation in respect of the working bandwidth (13.8 GHz for the simulated and 14.9 GHz for the calculated). This could be attributed to the fact that, the middle and surface layers are not in full accord with honeycomb-structure employed in the theoretical assessment of the RAMM as their volume ratio is slightly greater than 50% [29]. Figure 9 shows the power loss density of the threelayered absorber at the frequency of 4 GHz and Figure 10 revealed that of 12 GHz in simulation.…”

“…Others are 10 GHz [34], 3.13 GHz [35] and 3.18 GHz [36]. Likewise, the referenced absorbers' operational bandwidth to thickness ratio of 7.204 [29], 9.745 [30] and 6.43 [32] are smaller than that of the modeled RAMM value of 13.029. The designed RAMM thus outclassed these broadband absorbers because the larger the ratio, the better the performance of the absorber [32].…”

“…A new type of thin and broadband three layers structure metamaterial absorbers [28] that achieved in excess of 12 GHz absorption bandwidth with reflectivity below −10 dB in the 2-18 GHz frequency range at a thickness of 1.8mm was reported. Likewise, a three-layered metamaterial absorber [29] intended for broadband radar absorption was fabricated by means of selective laser sintering 3D printing technology and optimized results indicated reflectivity below −10 dB in the frequency range from 8 GHz to 18 GHz at 2.89mm thickness. A composite absorbent consisting of carbonyl iron powder and nylon [30]was used to modeled a metamaterial absorber of 4.7 mm optimized thickness which results in a reflection loss below -10 dB from 4 to 18 GHz range.…”

This paper reports the design and simulation of a three layered cross-block structured radar absorbing metamaterial (RAMM). The effective electromagnetic parameters of the designed structure are highly dependent on its geometric dimensions, subsequently behaving as a metamaterial. COMSOL Multiphysics simulation software was used to analyze the frequency dependent absorption response of the designed RAMM. The input impedance of multilayered absorber and strong fluctuation theory equations are used to theoretically verify the absorption response of the RAMM. The simulated result showed that the reflectivity of the RAMM is below -10dB from 4.2 -18.0 GHz frequency band with absorber thickness of 4.2mm. The calculated reflectivity result is in close agreement with the simulated result, thus confirming the validity of the design. The operational bandwidth to thickness ratio of this RAMM was found to be 13.029 making it better than the recently reported one with a value of 9.745 and thus contributing significantly in overcoming the contradicting demand of broadband and thin thickness.

This study proposes the fabrication of an asymmetric woodpile metamaterial absorber using direct-ink-writing 3D printing technology. The prepared inks are compounded using two loss fillers: carbon black and carbonyl iron powder. The synergistic effect enhances the electromagnetic loss performance and the synergistic mechanism is analyzed. The designed asymmetric woodpile absorber has a wider bandwidth than a simple tetragonal woodpile, and the advantage presented by the asymmetric woodpile arrangement overcomes the local impedance mismatch. A simulation is then performed, which demonstrates that the designed asymmetric woodpile metamaterial with a thickness of 8.6 mm can achieve a À10 dB absorbing bandwidth in the frequency range of 3.9-18 GHz, and the maximum reflection loss reaches up to À39 dB. Additionally, the absorber exhibits excellent angular performance and the absorption bandwidth of the transverse electric polarization or transverse magnetic polarization waves can reach more than 10 GHz with incident angles from 0°to 50°. Furthermore, the manufacturing process of the absorber is simple, efficient, and inexpensive, which presents considerable potential for its widespread implementation in practical engineering applications.

and attracted tremendous attentions, due to their wide applications in civil fields such as communication devices and aerospace vehicles. [1][2][3] On one hand, owing to the great detection technique progress achieved in the frequency region from 2 to 40 GHz with wavelength on a millimeter scale, materials with ultrabroadband microwave absorption capability covering more than four bands are highly pursued. [4][5][6][7] On the other hand, considering components and devices always work at elevated temperatures more than 1000 °C especially for aerospace vehicle applications, materials with high-temperature microwave absorption and high mechanical performance are also urgently required. [8][9][10][11] Dielectric absorption ceramics, [12][13][14] especially SiC ceramic, [15][16][17][18] are highlighted on the basis of their advantages of chemical stability, high temperature resistance, and thermal stability, which make them potential candidates for ultrabroadband and high temperature microwave absorption applications. However, the major challenge of the SiC ceramic microwave absorber like many other singlecomponent ceramic absorbents, is lack of structural designs and optimization with a low reflection profile. [4,[19][20][21] Recently, several approaches, involving uniform electrical porous lossy ceramics [22][23][24] and artificial metastructures, [25][26][27] have been proved to be effective for designing and fabricating ultrabroadband microwave absorption materials. Particularly, ceramic metastructures open a new opportunity for microwave absorption by designing the artificial periodic patterned structure configurations, and finally creating multiple absorption peaks along with additional microwave scattering based on structural influence, leading to broadband absorption. [28,29] However, these artificial ceramic metastructures are usually complex-shaped in geometries, and it is extraordinarily difficult to obtain ceramic metastructures through traditional ceramic processing and manufacturing technologies, such as powder sintering [30,31] and colloidal processing. [32,33] It is therefore highly desirable to develop an advanced and versatile technique for achieving the microwave absorbing ceramic metastructure. Broadband microwave absorption is essential on the realms of electromagnetic compatibility and protection in civil applicationscenarios. However, coordination of material and structure is difficult without proper iterative design between material and structure resulting in insurmountable drawbacks of traditional microwave absorption medium operating under high temperature erosion. Herein, SiC metastructure is manufactured in bulk by stereolithographic 3D printing. The dielectric loss tangent of SiC sintered body is over 0.5 and up to 1.5 at most showing good electromagnetic energy dissipation properties. The optimized SiC metastructure with complicated suspended features achieves −10 dB broadband microwave absorption from 6.96 to 40 GHz at room temperature (RT) across total frequency range of 33.04 GHz.
