An instrument-panel dashboard for computing electromagnetic Green's functions near metallic slabs — Purcell factor, local density of states, surface-plasmon dispersion, Casimir–Polder potentials, and Keysight ADS substrate exports — all with live charts and KaTeX-rendered formulas.

Six analysis tabs

Instrument panel tabs

Each tab runs an independent backend call and renders its own live chart, formula block, and schematic. All tabs fail independently — one error doesn't blank the others.

 

Purcell Factor

Spontaneous emission rate enhancement near a metallic slab — both perpendicular and parallel dipole orientations plotted spectrally.

  • Energy-resolved Purcell spectra (perp + para)
  • Peak Purcell values and peak energies
  • Drude model dielectric response
 

LDOS

Local density of optical states as a function of energy and atom–surface separation, including a 2D LDOS(ω, d) heatmap.

  • Normalised LDOS spectrum (ldos_normalised)
  • Max LDOS enhancement + peak energy
  • Separation map via /ldos-map
 

Dispersion / SPP

Surface-plasmon-polariton dispersion relation: frequency vs in-plane wavevector, highlighting the light cone and SPP branch.

  • ω–k dispersion curves
  • Light-cone boundary overlay
  • SPP resonance identification
 

Casimir–Polder

Van der Waals / Casimir–Polder potential vs atom–surface separation, with physics commentary from the backend.

  • CP potential in meV and joules vs separation (nm)
  • Minimum potential value and location
  • Backend physics_note rendered inline
 

ADS Export

Export slab parameters as Keysight ADS substrate files for RF/microwave co-simulation workflows.

  • Touchstone (.s2p) file download
  • ADS substrate definition export
  • ADS netlist fragment export
 

Quantum Interpretation

Parameter-aware physics commentary from the v2 API — explains what the computed quantities mean for the specific slab and atom separation you entered.

  • Narrative, section-by-section, or structured sub-object format
  • Falls back to raw-JSON diagnostic view if shape is unexpected
  • Reuses the /greens-function call (no extra API hit)
