Abstract

The rigorous solution of the problem is presented. The boundary-value method is employed using the property of completeness of angular functions on the respective intervals. The scattered far-field (SFF) and back radar cross section (BRCS) of the structure are evaluated asymptotically. The scattered field characteristics in the case of an E-polarized plane wave are analyzed numerically with controlled accuracy. It is shown that a resonant increase of BRCS is observed when the cylinder is filled with dielectric.

电介质涂层轴向开槽圆柱对e极化电磁波的散射
给出了该问题的严格解。利用角函数在相应区间上的完备性,采用边值法。对结构的散射远场(SFF)和后雷达截面(BRCS)进行了渐近计算。对e偏振平面波的散射场特性进行了数值分析,精度可控。结果表明,当圆柱体中填充介质时,BRCS的谐振增大。
