摘　　要：该文指出电磁波吸材料和电磁波吸收体是二种不同的概念。分别讨论了它们的工作机理及描述其性能的物理量。电磁波吸收材料通常分为二类,一类是电损型材料,另一类是磁损型材料。一般来讲,电磁波吸收材料本身并不能吸收入射的电磁波而不反射它们。改进反射特性的最有效方法是采用电磁波吸收体。利用材料的电或磁损耗以及传播过程中的多次反射特性,电磁波能被材料吸收而不产生反射。Both electromagnetic wave absorber material and electromag-netic wave absorber are two different concepts. Their operation mechanismand physical quantity used to describe their characteristics will be discussed.The electromagnetic wave absorber materials are classified into two types:electric - loss - based materials, magnetic - loss - based materials. Generally.electromagnetic wave absorber materials cannot draw incoming electromagnet-ic waves without reflecting them. The most effective means of improving thereflecting characteristics is to use an electromagnetic ware absorber. Electricor a magnetic loss of the medium and propagation characteristics of multire-flections can be used to make electromagnetic waves absorbed by the materialwithout reflecting them.
