本文以金属偶极子阵列为基础,结合集总元件加载,设计了在吸收频带内具有一个传输窗口的rasorber。结果表明,在平面波法向入射时,传输窗口的插入损耗为0.06d B。同时,相比于传统的无耗频率选择表面,传输窗口低频及高频端的强反射在87.8%的百分比带宽内都得到了至少10d B的降低。
Based on the metal dipole array, a rasorber with a transmission window in the absorption band was designed based on the lumped element loading. The results show that the insertion loss of the transmission window is 0.06d B when the plane wave is incident normal to the plane. At the same time, the strong reflections at the low and high frequency ends of the transmission window have been reduced by at least 10d B over 87.8% of the percentage bandwidth, compared to the conventional choice of surface without loss of frequency.
