“…At present, there are many methods used to reduce RCS. For example, changing the shape and structure of the antenna, loading an absorption material, 1 using antenna matching technology, adopting a special element arrangement, 2 using a frequency selective surface (FSS), 3 polarization selective surface, 4 electromagnetic novel material, 5 anisotropic resistive metasurface, 6 fractal structure, and adopting a bionic structure.…”

In this paper, a new application scenario for the conformal reflectarray is proposed. A conformal reflectarray element composed of a split ring and two arcs acting as phase shift lines is adopted. The phase shift between 0° and 360° is achieved by adjusting the length of the two arc lines. A new phase distribution calculation method is proposed to achieve a 10‐dB enhancement of monostatic radar cross section (RCS) at 15° to 30° of the tail of the missile. Projectiles (missile body) with and without the conformal reflectarray are fabricated and measured. Measurement results showed that the projectile with the proposed conformal reflectarray achieves RCS enhancement in the angular range of 15° to 30°. Specifically, RCS enhancements of 17.6, 10.43, and 29.02 dB are achieved at 15°, 30°, and the design angle of 22.5°, respectively. This work is the first to apply a conformal reflectarray to RCS enhancement in a specific angular domain.

“…In fact, the fi rst analytical models of some simple artifi cial surfaces realized through sub-wavelength metallic strips can be dated back to the fi fties [14]. Models and design procedures were later generalized and extended to diff erent geometries [15][16][17][18], while more recently, the use of resistive metasurfaces was investigated for the design of electromagnetic absorbers and radar-cross-section reduction devices [19,20]. The current trend of this fi eld is focused on the design of tunable devices the complex surface impedance of which can be controlled in real time [21].…”

In this paper, we review our recent results about the theoretical modeling and the possible applications of optical metasurfaces made of arrays of spheroidal nanoparticles. We consider both the case of plasmonic and dielectric nanoparticles, and we show how their peculiar responses in the visible range make them plausible candidates for several innovative nanophotonic applications. We also show that the coupled dipole model allows properly homogenizing both these classes of metasurfaces, and understanding the eff ects of the geometrical parameters and material properties of their macroscopic optical response. The results of full-wave simulations are also reported to confi rm the eff ectiveness of the theoretical fi ndings.

“…The lossy layer of the BNFSA is nearly transparent at notch band, enabling that the space between the lossy layer and ground plane can also be utilized. Therefore, the patch antenna assembled with the ground plane of the BNFSA is proposed to achieve excellent low‐profile and low‐RCS performance . Meanwhile, Huang et al realize a 3‐D BNFSA by transforming the transmission resonator of the AFSS to reflection resonator, and the BNFSA is also utilized as the ground plane/reflector of a dipole antenna .…”

An active band‐notched frequency selective absorber (BNFSA) with switchable notch band is proposed in this article. The BNFSA is a two‐layer structure composed of a lossy layer at the top and a ground plane at the bottom, separated by an air spacer. The element of the lossy layer is a lumped‐resistor‐loaded metallic dipole with a parallel LC resonance structure, which is realized by complementary n‐shaped resonator (CnR) inserted in the center, and PIN diode is welded at two arms of CnR. The bias circuit printed on the back of the substrate of the lossy layer connects to anode and cathode of the diode by via hole and isolates by the inductor. Simulation results show that the notch bands are located at 4.50 and 6.81 GHz when the diode sets to ON and OFF, respectively. To validate the performance of switchable BNFSA, the prototypes are fabricated and measured, reasonable agreement between simulated and measured results is obtained.
