摘要:

我们提出了一种通用的策略,实现宽带控制任意散射体,通过多个相干光束。通过设计入射光束的相位和振幅,可以抑制主要的散射分波,使障碍物失去其在宽带频谱中的固有响应。相干光束产生一个有限的静态区域,在该区域内相应的电场强度和坡印廷矢量为零。作为一个解决方案,超越总和规则的限制,我们的方法也是不考虑固有的系统属性,以及外在的工作波长,提供了一个非侵入性的控制波障碍物相互作用的任何类型的形状。

英文摘要:

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.
