Thiook syematically presents the mo recent progress iability and control of impulsive syems with delays. Impulsive syems have recently attracted continued high research intereecause they provide a natural framework for mathematical modeling of many real-world processes. It focuses not only oimpulsive delayed syems, but also impulsive syems with delayed impulses and impulsive syems with event-triggered mechanism, including their Lyapunov ability, finite-time ability and input-to-ate ability synthesis. Special attentiois paid to the bilateral effects of the delayed impulses, where prehensive ability properties are discussed ithe framework of time-dependent and ate-dependent delays. New original work with event-triggered impulsive control and its applications imulti-agent syems and collective dynamics are also provided.

超表面编码结构是一种能对电磁波按照研究人员预先要求进行操控的新型人工介质，它为调控电磁波提供了一种新机制。《太赫兹超表面编码》主要研究将超表面编码结构引入太赫兹波段，通过设计不同几何形状、不同编码排布的超表面阵列结构实现对太赫兹波单波束、多波束、异常折射、漫反射、波束控制、降低雷达散射截面等功能。在此基础上，将可调谐材料(石墨烯、二氧化钒、液晶等)复合到超表面编码结构中，通过改变外部激励条件，实现对太赫兹波主动调控功能。《太赫兹超表面编码》共6章，内容主要包括：太赫兹波技术及超表面编码；太赫兹频率超表面编码；Pancharatnam-Berry 相位太赫兹超表面编码；结构可变形太赫兹超表面编码；可调谐太赫兹超表面编码；全介质超表面编码。
