摘要
为探讨纳米碳纤维作为烟幕粒子的红外消光特性,基于电磁场理论建立了细直的纳米碳纤维感应电流积分方程,并利用矩量法进行了求解,导出了纳米碳纤维散射场及吸收、散射和消光截面的计算式.通过与变分法的计算结果相比较,表明了该方法的有效性.利用该方法数值分析了纳米碳纤维红外消光截面与入射场波长、入射角、纤维长度和半径的关系,计算结果为纳米碳纤维用于红外烟幕干扰提供了理论依据.
To explore the applications of carbon nanofibers in passive interference by smoke screen,the integral equation of induced current for carbon nanofibers is established based the electromagnetic field theory. The method of moment （MOM） is used to solve the integral equation. The formulae of scattered field and extinction cross section are derived for carbon nanofibers. By comparing with variational method,our proposed method is proved to be valid. The relationships between infrared extinction cross section of carbon nanofiber and the wavelength,the angle of incidence,the fiber length and diameter are analyzed and calculated. The results provide a theoretical basis for the applicatrion of nanocarbon fiber in infrared smoke interference.
