Metasurface using multi-layer ceramic capacitors for monostatic radar cross section reduction with broader bandwidth

Abstract

In this paper, the metasurface using the multi-layer ceramic capacitors (MLCCs) for monostatic radar cross section (RCS) reduction with broader bandwidth is proposed. By adjusting the width and the thickness of the inner electrodes, and the gap between staggered electrodes of the MLCC, two types of unit cell structures, the reflection phases of which have a phase difference of 180°, are designed. Next, by arranging the MLCCs in checkerboard patterns, the monostatic RCS reductions are simulated. Finally, the simulated results of the reflection phase difference and monostatic RCS reductions are compared with the measured results.
