✨ Plasmon Resonance & Metamaterial Array

Interactive 3D plasmonics lab: a gold nanoparticle's free electrons oscillate collectively with incident light, its near-field enhancement mapped as a live heatmap around the particle and plotted as an extinction spectrum. Switch to a sub-wavelength split-ring-resonator array to watch the effective permeability flip negative near its LC resonance.

⚙ Under the hood

Drive a gold nanoparticle's free electrons with a tunable light wavelength and watch the collective plasmon oscillation and near-field heatmap peak sharply at resonance, then switch to a split-ring metamaterial array and watch its effective permeability flip negative near the ring's LC resonance.
