【摘要】 现代军事装备迫切要求研制轻、薄、宽的涂层雷达吸波材料,这是极为困难的事情.文章采用全貌分析方法研究薄层、宽带吸波材料需求的电磁参数分布集,利用网格图分析了吸波材料在相应频率下的电磁参数:εr,iε,μr,iμ与材料的厚度、反射率衰减的dB值之间的关系.通过分析不同频段下的电磁参数分布集,指出研制轻、薄、宽涂层吸波材料的技术途径是按各频段要求提高相应的磁损耗参数μi,而且是唯一的途径.更多还原

【Abstract】 Light,thin and broadband coated Radar Absorbing Material(RAM) is required urgently to use in modern martial equipment.However,it is difficult to develop the eligible RAM.Panorama Analysis Method is employed to study the distribution set of the electromagnetic parameters for the thin and broadband RAM,and network line is presented to analyze the relations between the electromagnetic parameters:εr,εi,μr,μi in respective frequency and the thickness of RAM,the attenuation of reflection coefficient.Results show that to obtain light,thin and broadband coated RAM,the lossy magnetic parameter μi in respective frequency should be increased,and it is the only one method.更多还原
