负index of refraction的物理根源

On the physical origins of the negative index of refraction

David W. Ward, Keith A. Nelson, Kevin J. Webb

摘要:

负折射率的物理起源来自于一个稀的微观模型,产生的结果是广义的稠密凝聚相极限。特别是,散射从一个薄片的电和磁偶极子驱动以上的共振是用来形成一个基本的描述为负折射。具有实际意义的是,损耗和色散隐含在微观模型中。虽然天然存在的负折射率材料不可用,但铁磁和铁电材料提供了器件设计机会。

英文摘要:

The physical origins of negative refractive index are derived from a dilute microscopic model, producing a result that is generalized to the dense condensed phase limit. In particular, scattering from a thin sheet of electric and magnetic dipoles driven above resonance is used to form a fundamental description for negative refraction. Of practical significance, loss and dispersion are implicit in the microscopic model. While naturally occurring negative index materials are unavailable, ferromagnetic and ferroelectric materials provide device design opportunities.
