Abstract
In this work, the Conjugate Match Algorithm (CMA) is employed for the first time to synthesize RCS reduction metasurfaces. CMA is applied to estimate the phase distribution of the metasurface that would result in a 10 dB RCS reduction of flat metal targets at normal incidence. The metasurface considered for the synthesis is of size 300 mm × 300mm with an inter-element spacing of λ/2 at 10 GHz. The phase distribution thus estimated is realized using crossed dipole elements. A MATLAB code uses these data to generate the metasurface CST file for simulation. On simulation, the synthesized metasurface provides a bandwidth of 49% over the frequency range 5.7 GHz– 9.4 GHz.
