论文摘要
我们从理论上研究了纳米颗粒的三维光子环境的层析成像重建。作为我们重建的输入，我们使用电子能量损失光谱（EEL）图来进行不同的旋转角度。我们对表面极化场的层析成像重建进行平滑和粗糙的纳米棒，并比较了状态的重建和模拟的光子局部密度，这些状态被证明是非常一致的。使用这些结果，我们批判性地研究了我们的层析成像计划的潜力，并讨论了未来发展的局限性和方向。
We theoretically investigate the tomographic reconstruction of the three-dimensional photonic environment of nanoparticles. As input for our reconstruction we use electron energy loss spectroscopy (EELS) maps for different rotation angles. We perform the tomographic reconstruction of surface polariton fields for smooth and rough nanorods, and compare the reconstructed and simulated photonic local density of states, which are shown to be in very good agreement. Using these results, we critically examine the potential of our tomography scheme, and discuss limitations and directions for future developments.
