Struct AntiReflectionCoating 

pub struct AntiReflectionCoating {
    pub n_substrate: f64,
    pub n_coating: f64,
    pub thickness_nm: f64,
    pub wavelength_nm: f64,
}

Single-layer quarter-wave anti-reflection coating.

Fields

n_substrate: f64

Refractive index of the substrate.

n_coating: f64

Refractive index of the coating layer.

thickness_nm: f64

Physical coating thickness [nm].

wavelength_nm: f64

Design wavelength (for quarter-wave condition) [nm].

Implementations

impl AntiReflectionCoating

pub fn new( n_substrate: f64, n_coating: f64, thickness_nm: f64, wavelength_nm: f64, ) -> Self

Create a new AntiReflectionCoating.

pub fn optimal_n(&self) -> f64

Optimal coating refractive index for zero reflection: n_c = sqrt(n_s).

pub fn reflectance(&self, wl_nm: f64) -> f64

Approximate reflectance of the coated surface at wavelength wl_nm [nm].

Uses the thin-film two-beam interference formula:

R = (r₁² + r₂² + 2·r₁·r₂·cos δ) / (1 + r₁²·r₂² + 2·r₁·r₂·cos δ)

where r₁ = (1 − n_c)/(1 + n_c), r₂ = (n_c − n_s)/(n_c + n_s), and δ = 4π·n_c·d / λ.
