摘要
通过在周期结构中加载集总电阻,能够有效吸收入射电磁波,减小目标RCS。给出了两种超薄吸波结构,都具有厚度薄、重量轻的特点。分析了两种吸波材料的吸波机理,给出了表面反射系数的计算公式。实际加工了两种吸波材料,并对其吸波性能进行了分析。
Lumped resistors are introduced to period structures to absorb the incident wave effectively,and this can reduce the RCS of target. Two absorbing structures, which are designed to be thin and light, are presented. The absorbing principle is analyzed and formulas of reflection coefficient are given. Samples of two absorbing material are fabricated and the absorbing performance is analyzed.
