论文摘要
我们提出了一种通用策略,通过多个连贯的光束实现对任意散射器的宽带控制。通过工程化入射光束的相位和振幅,可以抑制主要的散射部分波,从而使障碍物在宽带光谱中失去其内在响应。相关的相干光束会产生一个有限和静态区域,在该区域内,相应的电场强度和po弹向量消失。作为超出总规则限制的解决方案,我们的方法也是固有的系统属性以及外部工作波长的不管,为任何形式的波形交互提供了非侵入性控制。
We propose a universal strategy to realize a broadband control on arbitrary scatterers, through multiple coherent beams. By engineering the phases and amplitudes of incident beams, one can suppress the dominant scattering partial waves, making the obstacle lose its intrinsic responses in a broadband spectrum. The associated coherent beams generate a finite and static region, inside which the corresponding electric field intensity and Poynting vector vanish. As a solution to go beyond the sum-rule limit, our methodology is also irrespective of inherent system properties, as well as extrinsic operating wavelength, providing a non-invasive control on the wave-obstacles interaction for any kinds of shape.
