Abstract

The spectrum of slow electromagnetic waves (EMWs) existing in a left-handed medium based on a magnetoactive plasma metamaterial has been theoretically studied. The metamaterial under study is a strip waveguide completely filled with longitudinally magnetized cold electron plasma containing a periodic structure made from ideally conducting split-ring resonators. It is shown that there exists either one (ordinary) or two (ordinary and extraordinary) slow EMWs in a left-handed medium based on anisotropic plasma, depending on the chosen values of the split-ring resonator eigenfrequency and magnetic induction. It is found that the extraordinary EMW has a negative dispersion, while the dispersion characteristic of the ordinary EMW contains portions of both negative and positive dispersion.

基于磁活性等离子体超材料的左手介质中的慢电磁波

摘要

理论上研究了基于磁活性等离子体超材料的左手介质中存在的慢电磁波（EMW）的频谱。研究中的超材料是一种条形波导，完全充满了纵向磁化的冷电子等离子体，该等离子体包含由理想导电的开口环谐振器制成的周期性结构。结果表明，基于各向异性等离子体，在左手介质中存在一个（常规）或两个（常规和非常规）慢速电磁波，具体取决于开环谐振器本征频率和磁感应强度的选择值。发现非常规EMW具有负色散，而普通EMW的色散特性包含负色散和正色散的一部分。
