摘要
根据坐标变换理论和电磁隐身斗篷的设计方法,通过在斗篷层和介质之间增加互补媒质层实现二维不同形状信息可传递电磁隐身斗篷,并通过全波仿真验证了该斗篷具有隐身和信息可传递的特性。然后对二维圆柱形电磁隐身斗篷的散射场进行分析,根据麦克斯韦方程组和波动方程,求解隐身斗篷不同区域的电磁场。通过Mie散射理论和介质分界面上电磁场的边界条件,在理论上证明了隐身斗篷各区域的散射场为0,表明斗篷可以使雷达无法发现斗篷内的介质,即实现介质的完美隐身。
According to the coordinate transformation theory and the design method of the electromagnetic invisibility cloak,the two-dimensional different-shaped electromagnetic invisibility cloak with information transmissible can be achieved by adding a complementary medium layer between the electromagnetic invisibility cloak layer and the medium.The characteristics of invisibility and information transmission of the electromagnetic invisibility cloak are verified by full-wave simulation.Then the scattering fields of the two-dimensional cylindrical electromagnetic cloak are analyzed,and the electromagnetic fields in different areas of the cloak are solved according to Maxwell's equations and wave equations.Through the Mie scattering theory and the boundary conditions of the electromagnetic field on the interface of the medium,it is theoretically proved that the scattering fields of each area of the invisibility cloak are zero,indicating that the cloak can prevent the radar from discovering the medium in it,that is,to realize the perfect stealth of the medium.
