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.
