Tip-enhanced Raman spectroscopy

submitted by: Maxim_Sukharev

2D cut of complete 3D simulations of gold tip and gold surface (tip-to-surface distance is 10 nm) excited by a laser pulse at 652 nm. Laser pulse propagates towards the screen and is polarized along tip's longer axis. Intensity is plotted in logarithmic scale and is normalized to it's maximum. Maximum intensity enhancement in this example is 4 orders of magnitude.
