摘要:

数值研究了金属薄膜中的亚波长圆孔及其周围纳米结构的光传输特性。数值结果与频域有限元法。所获得的可观的数值误差收敛到非常低的水平证明。非常好的协议,从文献中的实验结果,并证明了该方法的效用的几何参数的影响,通过孔径增强传输的调查。

英文摘要:

Light transmission through circular subwavelength apertures in metallic films with surrounding nanostructures is investigated numerically. Numerical results are obtained with a frequency-domain finite-element method. Convergence of the obtained observables to very low levels of numerical error is demonstrated. Very good agreement to experimental results from the literature is reached, and the utility of the method is demonstrated in the investigation of the influence of geometrical parameters on enhanced transmission through the apertures.
