Visualizing nk Data¶

Importing Libraries¶

Importing visualize_material_properties function from tmmax.data is sufficient for data visualizations.

import jax.numpy as jnp
from tmmax.data import visualize_material_properties
import matplotlib.pyplot as plt

## Refractive Index and Extinction Coefficient as a Function of Wavelength

As of May 6, 2025, the visualizations of all materials available in the tmmax database are provided below. We can visualize the refractive index (n) and extinction coefficient (k) as a function of wavelength. This uses data from the internal nk database and plots it with dual y-axes (n on left, k on right)

## Logarithmic Scale Axis

Either axis can be converted to a logarithmic scale using the logX and logY flags.

## Refractive Index and Extinction Coefficient as a Function of Photon Energy

You can also display the x-axis in terms of photon energy instead of wavelength. To do this, simply enable the eV flag.
