摘　　要：研究了某型石墨烯泡沫材料不同厚度、不同介电常数实部、不同介电常数虚部对表面波衰减常数的影响,并利用电磁仿真软件验证了结果的正确性。研究结果表明:厚度变大、介电常数实部变小、虚部变大可以减小表面波衰减常数截止频带的宽度。工程实践中,RCS减缩受镜面反射、电损耗、行波抑制等多个因素共同影响,需要对具体的目标结构展开针对性分析。The influence of different thickness,real and imaginary parts of different dielectric constant on the surface wave attenuation rate of a certain type of Graphene foam material was studied.And the correctness of the results was verified by electromagnetic simulation software.The results show that the width of cutoff frequency band of surface wave attenuation constant can be reduced by increasing thickness,decreasing real part of dielectric constant and increasing imaginary part.In engineering practice,RCS reduction was affected by many factors such as mirror reflection,electrical loss and traveling wave suppression coefficient,and it is necessary to carry out targeted analysis on specific target structure.
