How this service works
Recover a complete coupled periodic-grating diffraction artifact with its modal power ledger.
Output
Returns a complete coupled periodic-grating diffraction artifact including the full modal power ledger — a structured breakdown of diffraction efficiencies (reflected and transmitted power) for each diffraction order computed via RCWA, along with the recovered field and energy distribution data across all harmonics.
Example use cases
Photonic grating diffraction efficiency simulation
“I need the full diffraction energy ledger for a sinusoidal dielectric grating: period 1.0 µm, vacuum wavelength 0.85 µm, layer thickness 0.3 µm, incident angle 0.0 rad, incident index 1.0, transmitted index 1.8, 7 harmonics, and permittivity cosine coefficients [3.0, 0.8]. Show me how power is split across all diffraction orders.”
Anti-reflection grating design validation
“Check the modal power distribution for my anti-reflection grating design — period 0.4 µm, wavelength 0.5 µm, layer thickness 0.1 µm, 5 harmonics, incident index 1.0, transmitted index 1.45, incident angle -0.2 rad, and permittivity cosine coefficients [2.1, 0.3, -0.05]. I want to confirm the energy is going mostly into the zeroth transmitted order.”
Oblique incidence grating scattering analysis
“Compute the Fourier-Maxwell diffraction artifact and modal energy ledger for a TE grating at oblique incidence: vacuum wavelength 1.55 µm, period 2.0 µm, layer thickness 0.5 µm, incident angle 0.6 rad, incident refractive index 1.0, transmitted refractive index 2.5, 3 harmonics, and permittivity cosine coefficients [6.25, 1.2, -0.3, 0.05].”

POSThttps://detect.halowerk.com/v1/F-TD2000-GEO-INDUSTRY-B011/periodic-te-grating-coupled-fourier-maxwell-diffraction-energy-ledger?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need rigorous coupled-wave analysis (RCWA) results for a one-dimensional periodic TE-polarized diffraction grating with cosine-modulated permittivity, and require the full modal power ledger across all diffraction orders. It is well-suited for photonics design validation, anti-reflection grating optimization, and electromagnetic scattering simulation at optical wavelengths. Prefer this over approximate methods (thin-film transfer matrix, scalar diffraction theory) when you need exact electromagnetic field solutions with multiple harmonics.
Side effects
- Invalid harmonic_count (must be 3, 5, or 7) returns validation error
- period or vacuum_wavelength out of range [0.1, 10] returns schema error
- incident_angle outside [-0.8, 0.8] rad returns out-of-range error
- permittivity_cosine_coefficients array exceeds 4 items or values outside [-10, 10] returns validation failure
- layer_thickness below 0.001 or above 2 returns bounds error
- Missing required RCWA data fields returns 400 bad request
- Payment not attached or insufficient USDC causes 402 Payment Required
