RCS reduction metasurface based on orbital angular momentum
A novel radar cross-section (RCS) reduction metasurface is designed, fabricated, and experimentally characterized to flexibility control wavefront and efficiency generated orbital angular momentum (OAM). The metasurface is composed of several square loops with different reflection phases. Utilizing...

| description | A novel radar cross-section (RCS) reduction metasurface is designed, fabricated, and experimentally characterized to flexibility control wavefront and efficiency generated orbital angular momentum (OAM). The metasurface is composed of several square loops with different reflection phases. Utilizing the property of the OAM phase singularity, the metasurface presents a significant RCS reduction along the propagation axis. Simulation results show that RCS reduction over 40 dB for normal incident plane waves at 7.6 GHz. For further clarity the physical mechanism of the RCS reduction, the near-field and 3D far-field features of the metasurface are discussed in detail. Two prototypes are fabricated and experimented with different topological charges. Good agreement is achieved between full-wave simulations and measurements. The design methodology provides an alternative to low-RCS and wavefront modulation design. |
