利用零空间介质扩展相控阵天线的扫描角
Extending the scanning angle of a phased array antenna by using a null-space medium
摘要：
通过引入柱形零空间区域作为参考空间，设计了一种天线罩，该天线罩可以使相控阵天线的扫描角按预定的关系（如入射角和偏转输出角之间的线性关系）扩展。经过一些近似，我们只需要两个均匀的材料来构建建议的天线罩逐层。这种介质被称为零空间介质，它已经被研究和制造用于实现超透镜和其他一些设备。数值仿真验证了天线罩的性能。
英文摘要：
By introducing a columnar null-space region as the reference space, we design a radome that can extend the scanning angle of a phased array antenna (PAA) by a predetermined relationship (e.g. a linear relationship between the incident angle and steered output angle can be achieved). After some approximation, we only need two homogeneous materials to construct the proposed radome layer by layer. This kind of medium is called a null-space medium, which has been studied and fabricated for realizing hyper-lenses and some other devices. Numerical simulations verify the performance of our radome.
