平面界面中表面等离子体激元的传播

Propagation of surface plasmons through planar interface

Tomas Vary, Peter Markos

摘要:

我们分析了入射到两个平面界面的表面等离子体激元的散射。通过使用由Oulton等人[Phys.Rev.B76,035408(2007)]开发的散射矩阵技术,我们计算了倾斜入射角的透射、反射系数和辐射损耗。我们发现,表面波通过两个表面之间的单一界面的传输可能伴随着10- 40%的等离子体能量的辐射损失。

英文摘要:

We analyze the scattering of the surface plasmon incident at a planar interface between two dielectrics. By using the scattering matrix technique, developed by Oulton et al. [Phys. Rev. B 76, 035408 (2007)], we calculate the transmission, reflection coefficients and radiative losses for oblique incident angles. We found that the transmission of a surface wave through a single interface between two dielectrics may be accompanied with radiation losses of 10-40 per cent of the plasmon energy.
