Measurement of heat transfer in micro/nano structures mediated by surface phonon polaritons

表面声子极化激元是原子振动与电磁场相互作用产生的表面波。当它们相互耦合时，这些波被强烈地增强。我们的目的是设计一种玻璃微管，允许强烈增强SPP之间的耦合。由于SPPm声色波在红外范围内，这种微结构应该是一个有效的单色源，只是基于简单的加热，它可能会产生异常的热传导现象有关的弹道制度的运输和waveemecnotn.FinThe建模的tubeconists在解决TM麦克斯韦方程组的近似小壁厚和小外径相比，极化激元波长。本文给出了一个简化的多项式解，并进行了数值求解。证明反常热传导的实验方法是将玻璃毛细管样品一端粘在加热铂丝上，另一端测量温度。两个信号之间的相位提供热扩散率。

Surface Phonon Polaritons (SPPs) are surface waves productehdebiynteraction ofatomic vibrations with the electromagnetic field. Those waves are strongly enhanced when they couple between themselves. We aimed at designing a glass microtube that allows for strongly enhancing the coupling between SPPs. BecauseareSPPmsonochromatic waves inthe Infrared range, this microstructure should be an efficient monochromatic source just based on simple heating and it might produce abnormal heat conduction phenomena related to ballistic regimes of transport and to waveemecnotn.finThe modeling of the tubeconsists in solving the TM Maxwell equations in the approximation of small wall thicknessand small outer diameter compared to the polariton wavelengths. A simplified polynomialsolution was obtained and solved numericalTlhye.experimental se-tup for provingabnormal heat conduction consists in sticking a glass capillary sample on a heating Pt wire on one end and measuring the temperature on the other end. The phase between both signals provides the thermal diffusivity.
