讲座摘要：

“0”是一个有趣的数字，“0”是与“∞”相反的另一种极限；在电磁学领域，我们是否可以从“0”出发，获得趋于“∞”的性能，孵化出新的技术与理论。本报告从一类特殊的ENZ（epsilon-near-zero）媒质入手，研究该类电磁媒质特殊的基础特性。基于ENZ媒质，讨论多种技术方法，可应用于电磁学中的不同领域，实现某种极限的性能。

“0” is an interesting number, as an extreme quantity opposite to “∞”. In the study of electromagnetics, based on extreme parameters, can we invent or develop new techniques to have infinite property? In this talk, we will talk about a class of extreme-parameter medium, named as epsilon-near-zero (ENZ) medium, and some interesting techniques with some infinite characteristics are proposed and discussed, such as doping method and antenna design.
