电阻渐变型结构吸波材料的研究与发展

结构吸波材料的发展建立在先进复合材料发展基础之上,融受力与吸波为一体,将新的吸波机制(如电阻片、电路模拟、手征媒质等)引入到结构吸波材料的研制中,可制备全新的结构吸波材料.电阻渐变型结构吸波材料具有优良的电结构可设计性,通过控制材料的类型(电介质或磁)、厚度、损耗系数及阻抗等,能够使雷达吸波材料具有宽频吸收效果,并可根据不同部位选择不同的结构形式,具有广阔的应用前景.

Development of resistance gradual variation radar-absorbing composites

The development of structural absorbing materials is based on the development of advanced compo sites and compose the abilities of radar absorbing an d standing loading. It can make new kind of structural absorbing materials by using new absorbing theory (such as resistance gradual variation piece,circuit analogue, chiral structure). The resistance gradual variation radar absorbing composites have good character of radar absorbing designing and can obtain wide band absorbing property through controlling the type (dielectric or magnetic),thickness, loss coefficient and so on. The different structure form can be chosen for different region . The resistance gradual variation radar absorbing composites have broad perspective.
