It is shown how a recently proposed method of cloaking is effective over a broad range of frequencies. The method is based on three or more active devices. The devices, while not radiating significantly, create a "quiet zone" between the devices where the wave amplitude is small. Objects placed within this region are virtually invisible. The cloaking is demonstrated by simulations with a broadband incident pulse.
研究表明，一种最近提出的隐身方法在很宽的频率范围内都是有效的。该方法基于三个或更多有源器件。这些器件虽然不会显著辐射，但会在器件之间创建一个“安静区域”，该区域内的波幅很小。放置在这个区域内的物体实际上是不可见的。通过对宽带入射脉冲的模拟演示了这种隐身效果。
