Abstract

The scope of this paper is to present a systematic and versatile method, with minimal computational requirements, that incorporates the use of new electromagnetic bandgap (EBG) structures in stealth technology. Grounded structures are used to ensure zero transmittance resulting to angle independence of the incident radiation. A possible future realistic scenario is simulated and experimentally examined where a metallic plane is fully covered by EBG structures and the monostatic radar cross section is measured. Varying the angle of incidence from 0 ° to 90 °, it is observed that for the worst case scenario the reduction of the monostatic radar cross section (RCS) is almost 19 dB. Finally, to verify our idea, the RCS of a metallic cube also fully covered by EBG structures was examined. The assets of the proposed concept, applied to the design of different patterns, appear to be potentially beneficial for various electromagnetic interference/electromagnetic compatibility configurations.
