Struct AbsorptionCoefficient 

pub struct AbsorptionCoefficient {
    pub alpha: f64,
}

Beer-Lambert absorption model: I(z) = I₀ exp(-α z).

Fields

alpha: f64

Absorption coefficient α (m⁻¹).

Implementations

impl AbsorptionCoefficient

pub fn new(alpha: f64) -> Self

Construct from absorption coefficient in m⁻¹.

pub fn from_extinction(k: f64, lambda_m: f64) -> Self

Construct from extinction coefficient k and wavelength λ (m).

α = 4π k / λ

pub fn intensity(&self, i0: f64, z: f64) -> f64

Transmitted intensity after propagating distance z (m).

pub fn penetration_depth(&self) -> f64

Penetration depth δ = 1/α (m).

pub fn absorbance(&self, z: f64) -> f64

Absorbance A = α z (dimensionless, also known as optical density).
