摘要
报导了电磁导弹的初步实验.实验结果表明:单频连续波在瑞利距离之后的确表现为随距离的反平方律(r^(-2))衰减;与此不同,脉冲电磁波在离源较远时具有较慢的衰减规律(如r^(-2),0<ε<1).被称为“电磁导弹”的慢衰减电磁波无论在理论上,还是在工程应用上都具有相当重要的意义.
The preliminary experiment of electromagnetic(EM)missiles is reported.The experimental results show that a single-frequency continuous wave does decay as the inverse square law of the distance(r^(-2))alter the Rayleigh distance,and in contrast,a pulsed EM wave decreases more slowly as r^(-2(?))(0<ε<1).Such EM missiles are of great significance both in theory and in engineering applications.
