snompy.sample.permitivitty#

sample.permitivitty(beta, eps_i=1 + 0j)#

Return the permittivity of a material based on its quasistatic reflection coefficient.

Calculated using eps_i * (1 + beta) / (1 - beta), where eps_i is the permitivitty of the preceeding material, and beta is the quasistatic reflection coefficient of the sample.

Parameters:
betacomplex

Quasistatic reflection coefficient of the sample.

eps_icomplex, default 1.0

Dielectric function of material i (the preceeding material).

Returns:
eps_jcomplex

Permitivitty of material j.
