Classes

IdealMaterial(n[, k, propagation_model])

Represents an ideal material with a fixed refractive index and extinction coefficient for all wavelengths.

class IdealMaterial(n: float, k: float = 0, propagation_model: BasePropagationModel | None = None)[source]#

Represents an ideal material with a fixed refractive index and extinction coefficient for all wavelengths.

Variables:

index (float) – The refractive index of the material.
absorp (float) – The extinction coefficient of the material.

abbe() → float#

Calculate the Abbe number (Vd) of the material.

The Abbe number is a measure of the material’s dispersion, defined as Vd = (n_d - 1) / (n_F - n_C), where n_d, n_F, and n_C are the refractive indices at the Fraunhofer d (587.5618 nm), F (486.1327 nm), and C (656.2725 nm) spectral lines, respectively.

Returns:: The Abbe number of the material.
Return type:: float

classmethod from_dict(data)[source]#

Creates a material from a dictionary representation.

Parameters:: data (dict) – The dictionary representation of the material.
Returns:: The material.
Return type:: IdealMaterial

k(wavelength: float | be.ndarray, **kwargs) → float | be.ndarray#

Calculates the extinction coefficient at a given wavelength with caching.

Parameters:

wavelength (float | be.ndarray) – The wavelength(s) of light in microns. Can be a float, numpy array, or torch tensor.
**kwargs – Additional keyword arguments for calculation.

Returns:

The extinction coefficient at the given wavelength(s).

Return type:

float | be.ndarray

n(wavelength: float | be.ndarray, **kwargs) → float | be.ndarray#

Calculates the refractive index at a given wavelength with caching.

Parameters:

wavelength (float | be.ndarray) – The wavelength(s) of light in microns. Can be a float, numpy array, or torch tensor.
**kwargs – Additional keyword arguments for calculation (e.g., temperature).

Returns:

The refractive index at the given wavelength(s).

Return type:

float | be.ndarray

to_dict()[source]#

Returns a dictionary representation of the material.

Returns:: A dictionary representation of the material.
Return type:: dict
