“…With the rapid development of technology, electromagnetic (EM) interference has become a serious problem (Cao et al, 2018;Jia et al, 2018;Wei et al, 2018b;Wu G. et al, 2018;, which not only causes damage to the operation of electronic devices, but also has a remarkable negative effect on human health (Liang et al, 2016(Liang et al, , 2018Oraizi et al, 2016;Smitha et al, 2016;Tian et al, 2017;Meng et al, 2018). The key to solve this problem relies on the development and application of EM wave absorbing materials (Batrakov et al, 2016;Liu T. et al, 2016).…”

Electromagnetic (EM) wave absorbing materials are strongly desired for the reason that EM pollution has become a serious problem with the rapid development of modern technology, which brings harm to the environment and human health. Herein, nanocomposites of Sn/reduced graphene oxide (Sn/rGO) as a novel type of EM absorbing materials were synthesized via a facile and efficient strategy. Nanoscale SnO 2 microspheres were synthesized by sol-gel method, and the Sn/rGO composites were obtained after hydrothermal process with GO. Samples with different Sn content were fabricated (rGO:Sn = 30:1, 20:1, 10:1, mass ratio), and their EM wave absorption performance were analyzed. By changing the mass ratio of Sn and rGO, dielectric constant of the composites can be adjusted, and better impedance matching can be achieved. The unique capacitive structure and conductive network enable the material to have strong dielectric loss and excellent absorption performance. This research offers a new route for designing and fabricating high-frequency EM wave absorbing materials.

“…During some studies investigating the backscattering reduction of the spherical conducting body of revolution, a certain potential for the backscattering enhancement was briefly mentioned. Examples are dielectric shell and plasma sheath, [36][37][38][39][40][41] conducting post loading, 42,43 replacement of solid spheres by spherical wire frames, 44,45 and wrapping of parallel wires around the spherical surface. 46 In addition, the replacement of a solid cone by wire frames, 47 the right angle reflecting step at the cone base, 48 and discontinuities on the cone body such as corrugation 49 and groove 50 were intentionally introduced to augment the backscattering cross-section from the conical conducting body of revolution.…”

The focus of this paper is on phase gradient metasurfaces conformal to spherical and conical bodies of revolution, with an aim of engineering retroreflections and therefore augmenting backscattering cross-sections of those three-dimensional geometries under the illumination of a plane electromagnetic wave. Based on the conducting sphere and cone, the effect of the geometric revolution property on the selection of the unit inclusion of metasurfaces is considered. The procedure for using the selected unit inclusion to implement the proper reflection phase gradient onto the illuminated surfaces of those objects is formulated in detail. Retroreflections resembling conducting plates under normal incidence are observed for both the conducting sphere and cone coated with conformal metasurfaces. As a result, the redirection-induced retroreflection effectively contributes to the backscattering cross-section enhancement. A good agreement between full-wave simulations and measurements demonstrates the validity and effectiveness of backscattering cross-section enhancement using spherical and conical metasurfaces.
