摘要

超振荡现象在显微镜、天线设计和材料科学中引起了极大的兴趣。这种现象已经被推广，并产生了超移的概念，这是一个深远的扩展，适用于可能出现不连续导数的函数。从这个角度来看，这是一个可能具有重要应用的概念。本文将对超移概念与分析性概念之间的复杂联系提供最新的报告。

Supershift properties for nonanalytic signals

The phenomenon of superoscillations is of great interest in microscopy, antenna design, and material sciences. This phenomenon has been generalized and has given rise to the concept of supershift, which is a far reaching extension that applies to functions that may present discontinuous derivatives. From this perspective, this is a notion that might have significant applications. This paper will provide an up to date report on the complex connections between the concept of supershift and that of analyticity.
