Chiral Plasmonic Nanohelix: Circular Dichroism (2D Helical Wheel)

2D helical-wheel coupled-dipole simulator of a chiral gold nanoparticle helix: watch induced plasmon dipole phasors respond differently to left- and right-circularly-polarized light on an unrolled polar map, and see the resulting circular dichroism spectrum.

Same coupled-dipole physics as the 3D nanohelix simulator, read out through a genuinely 2D-native diagram: a helical-wheel phasor map that unrolls the helix's azimuthal winding onto concentric turns instead of rendering a 3D scene. Each gold nanoparticle's self-consistently solved induced dipole is drawn as a phasor whose brightness is |pᵢ| and whose short radial tick marks its complex phase; flipping the helix handedness mirrors the whole phase pattern and flips the sign of the plasmonic circular-dichroism spectrum, CD(λ) = A(LCP) − A(RCP), shown live alongside it.

⚙ Under the hood

2D helical-wheel coupled-dipole simulator of a chiral gold nanoparticle helix: watch induced plasmon dipole phasors — unrolled onto concentric turn rings instead of a 3D render — respond differently to left- and right-circularly-polarized light, alongside a live plasmonic circular dichroism spectrum.
