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.
