摘要

金属纳米粒子的光学性质由于其广泛的应用前景，在纳米光学领域得到了广泛的研究。在这项工作中，我们通过数值模拟来探索金属纳米粒子的光学性质，以衰减窗口中的红外辐射。采用边界元法(BEM)求解麦克斯韦方程组进行了数值模拟。模拟了金、银和铝纳米棒，以及银纳米三角形。模拟结果和数值计算表明，对于金、银纳米棒和银纳米三角形而言，在可见光范围内具有较高的透过率，而在波长为700 nm ~ 1575 nm(对应于大部分来自太阳的红外辐射)之间具有较强的衰减。我们的研究结果为红外阻挡窗的设计提供了有用的细节。

Metallic Nanoparticles for Infrared-Blocking Windows

The optical properties of metallic nanoparticles are widely studied in nanooptics due to the multiple applications that can be developed. In this work we explore, by means of numerical simulations, the optical properties of metallic nanoparticles in order to attenuate the infrared radiation in a window. The simulations were carried out by solving the full Maxwell equations using the boundary element method (BEM). Gold, silver and aluminum nanorods were simulated, as well as silver nanotriangles. The simulation results and numerical calculations show a high transmittance in the visible range and a strong attenuation at wavelengths between 700 nm and 1575 nm (which corresponds to most of the infrared radiation coming from the sun) for the case of gold and silver nanorods and for silver nanotriangles. Our results provide useful details for the design of infrared-blocking windows.
