Optical Dispersion Relations
Features
- A collection of exact and approximate optical dispersion relations.
- Academic Sources eg textbooks and journal articles.
- Fully tested (see
test/) so users can calculate with confidence.
Examples
- Silver permittivity can be calculated with a Single Pole Drude-Lorentz model:
silver_dispersion = drude_lorentz.DrudeLorentz().with_angular_frequency(
angular_frequency
).with_plasma_frequency(1.35e16).add_pole(
damping_constant=0.0023*1.35e16
)
silver_permittivity = silver_dispersion.permittivity()- Gold permittivity can be calculated with a Double Pole Drude-Lorentz model:
gold_dispersion = drude_lorentz.DrudeLorentz().with_dielectric_constant(
6
).with_angular_frequency(angular_frequency).add_pole(
peak_strength=6*5.37e15**2,
damping_constant=6.216e13,
).add_pole(
peak_strength=6*2.263e15**2,
damping_constant=1.332e15,
peak_position=4.572e15
)
gold_permittivity = gold_dispersion.permittivity()- More examples can be found under
/examples/.
