Simplistic metasurface design approach for incident angle and polarization insensitive rcs reduction [PDF]

open access: yesScientific Reports
This paper proposes the design of a metasurface for polarization and incident angle-insensitive RCS reduction applications. An ellipse-shaped unit cell is utilized as a polarization converter, which is then arranged to form a checkerboard surface.

Broadband RCS Reduction of Antenna with AMC Using Gradually Concentric Ring Arrangement [PDF]

open access: yesInternational Journal of Antennas and Propagation, 2017
This paper proposes a new method to the broadband RCS reduction with the artificial magnetic conductor (AMC) surfaces. The AMC surfaces can introduce a zero-degree reflection phase shift to incident waves. The phase difference between the antenna and AMC
