The electron cloud in an atom may accept or return the energy offered by electromagnetic induction in a quantization way. Correspondingly, the equivalent induced current on the electron cloud and its energy assume discrete values.

本文从金属的高损耗特性出发,研究电磁波在金属中的传播。由于电磁波在介质-金属表面的强反射,很多人认为电磁波不能在金属中传播,也就忽略了金属中波长的研究。本文借助于反射和折射定律,推导了电磁波在金属中的传播模式及金属中波长的计算公式,并证明了介质-金属界面不存在全反射。

本文作者曾总结出了大气窗口公式。通过讨论认为,由该公式计算出的大气水分子电磁波吸收波谱图与大气窗口图基本吻合。从而从理论上证明大气分子的电磁波吸收主要由水分子产生。本文对水分子的电磁波吸收机理做了进一步所的探讨。所得到的新模型比作者早期建立的模型更具有说服力。

本文通过水热反应法,利用去离子水作为溶剂,合成出了单分散且尺寸在微米级的镍实心球状结构,并用于电磁波吸收材料。样品的结构通过X射线衍射(XRD)表征,其微观形貌通过扫描电子显微镜(SEM)观察。电镜图像显示,镍实心球状结构的尺寸为3-4 μm。含有50 wt%镍实心球的环氧树脂复合材料具有较好的电磁波吸收性能(RL < -20 dB),吸波频率范围为1.6-4.0 GHz,吸波厚度为3.4-8.0 mm。
