利用相位和振幅补偿聚焦波的一般方法

General method for focusing of waves using phase and amplitude compensation

Lars Egil Helseth

摘要:

基于相位和振幅补偿的波聚焦的一般方法适用于单色波、多色波和扩散波。单色波可以在自由空间中形成空间局部化的波,而多色波形成与介质中的亚波长区域相连的非衰减行进消逝模式,其中频率取决于波矢量。我们提出了一个类比之间的相位补偿方法和惯性,相对论坐标系之间的频率变换。

英文摘要:

A general method for focusing of waves, based on phase and amplitude compensation, is applied to monochromatic, polychromatic and diffusive waves. Monochromatic waves may form spatially localized waves in free space, whereas polychromatic waves form non-decaying traveling evanescent modes conned to subwavelength regions in media where the frequency depends on the wave vector. We suggest an analogy between the phase compensation method and the transformation of frequencies between inertial, relativistic coordinate systems.
