摘要

为了实现三维隐身，提出了一种适用于大型独立散射体的被动球面隐身技术。球面斗篷的特点是空间调制的不可穿透张量表面电抗，将入射平面波转换成表面波，将能量传递到阴影侧。平面波前的漏波连续向前散射，以消除球后的阴影。4波长半径球形斗篷的数值设计和仿真验证了该斗篷在减小各方向散射方面的有效性。

A Modulated Reactance Spherical Surface Cloak for 3-D Invisibility

Toward practical 3-D invisibility, passive spherical surface cloaking applicable to large, freestanding scatterers is presented. Characterized by a spatially modulated impenetrable tensor surface reactance, a spherical surface cloak converts the incident plane wave on the lit side into surface waves that carry power to the shadow side. Leaky waves of planar wavefronts are continuously shed in the forward direction to remove the shadow behind the sphere. Numerical design and simulation of a 4-wavelength-radius spherical cloak confirm the effectiveness in minimizing scattering in all directions.
