基于坐标变换理论,提出并推导了正N边形柱的隐身条件,并得到了相应隐身罩材料本构参数张量的通解表达式.根据导出的本构参数张量,利用电磁仿真软件分别对N取不同值时的三个典型算例进行仿真验证.仿真结果证实了所得到的本构参数张量的正确性.考虑到损耗对于隐身效果的影响分析,这些分析结果为隐身物理机理的进一步理解,以及降低对称度隐身罩的设计奠定了理论基础.
Based on the coordinate transformation theory, the stealthy condition of the positive N-shaped column is proposed and deduced, and the generalized expression for the constitutive parameter tensor of the cloak is obtained.According to the derived constitutive parameter tensor, N to take different values of the three typical examples of simulation verification.The simulation results confirm the correctness of the constitutive parameters obtained.Taking into account the impact of loss on the stealth effect analysis of these results for the stealth physics and further Understanding, and reducing the symmetry of the cloak design laid the theoretical foundation.
