本文的范围是提出一种系统和通用的方法，以最小的计算需求，将新型电磁带隙（EBG）结构应用于隐身技术。接地结构用于确保零透射率，从而使入射辐射与角度无关。模拟和实验研究了一种可能的未来现实场景，其中金属平面完全被EBG结构覆盖，并测量了单基地雷达的横截面。将入射角从0度变化到90度，观察到在最坏情况下，单基地雷达截面（RCS）的减少几乎为19 dB。最后，为了验证我们的想法，我们对同样被EBG结构完全覆盖的金属立方体的RCS进行了测试。将所提出的概念的优点应用于不同模式的设计，似乎对各种电磁干扰/电磁兼容配置都有潜在的好处。
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 degrees to 90 degrees, 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.
