摘要：

communication shows how to reduce the radar cross section (RCS) by employing two artificial magnetic conductor (AMC) metasurface unit cells. The two AMCs cells are arranged in chessboard configuration to decrease both monostatic and also bistatic RCS using low-cost FR4 material. A 10 dB reduction in RCS can be obtained when the difference in phase between the reflected wave from AMC1 and AMC2 will be (180 degrees +/- 37 degrees) to make the waves that reflect from AMC1 and AMC2 interfere destructively. A significant reduction in RCS of checkerboard metasurface can be observed. The measured X-pol and Y-pol monostatic RCS of the proposed chessboard surface indicate that the reduction in RCS is over a frequency band from 23.71 to 33.52 GHz for X-pol and from 25 to 37.8 GHz for Y-pol with a maximum reduction in RCS of -27 dB for X-pol and maximum reduction of -25.9 dB for Y-pol. The bistatic RCS of the chessboard metasurface is also reduced and the incident plane wave scatters into five lobes in different directions.
