摘　　要：传统复合吸波材料存在低频特性差、与铁氧体阻抗匹配困难等问题。简述了一种全新的陶瓷型吸波尖劈工作原理,并列举了与铁氧体配合使用时的吸波损耗特性。总结了陶瓷型吸波尖劈的优势,并给出其在标准三米法暗室中的应用案例,检测结果显示归一化场地衰减优于±2.5 d B,场地电压驻波比小于5.0 d B。The disadvantages of traditional hybrid absorber, such as poor performances in low frequency and on matching with ferrite tiles, are summarized.A novel kind of ferrite absorber is introduced based on its wave-absorbing mechanism, and its absorbing characteristics combined with common ferrite tile are illustrated.The advantages of the new type ferrite absorbing wedge are finally concluded with the site validation results of normalized site attenuation(NSA) and site voltage standing-wave ratio(SVSWR) from a 3-m anechoic chamber.
