Abstract

Herein, a new method to control radar cross section (RCS) is proposed based on active metasurfaces. By means of the varactors, the metasurface can control the reflected beam and RCS. The incident beam can be scattered into four directions with lower RCS values or scattered into two directions or directly reflected back with higher RCS values. The simulated results verified the design. The work has potential value in backscattering enhancement and RCS reduction.
