摘要
在吸波材料的设计中传输线理论是被广泛采用的一种理论方法。文章重点分析传输线理论计算中所体现的多吸收峰现象,得出产生这些吸收峰的原因是电磁波的干涉作用引起,并指出吸波材料的厚度匹配问题,实质上就是解决材料厚度与干涉相消的关系,同时提出了水泥基吸波材料一些厚度匹配优化建议。
Transmission line theory have been widely used in the field of absorbing materials design.A great deal of absorption peaks brought in calculation are discussed.Analyzing results suggest that the large number of absorption peaks are caused by the interference of electromagnetic wave and the thickness matching.Some optimizing thickness matching recommendations were also put forward.
