We consider propagation of surface plasmon polaritons in linear chains of equidistant metallic nanospheroids. We show that, for suitably chosen parameters, the propagation is free of spatial decay in spite of the full account of absorptive losses in the metal.
我们研究了等间距金属纳米球链中表面等离激元极化激元的传播。我们表明，对于适当选择的参数，尽管金属中的吸收损耗被完全考虑在内，传播仍然没有空间衰减。
