This module provides a short list of utilities and complementary functions for the refractive index module.

Basic conversion from refractive index to dielectric permittivity (and viceversa) is implemented. The module also provides a conversion function from dielectric permittivity to radar dielectric factor K2 which is of great importance in radar applications

Rayleigh complex dielectric factor This is basically the K complex factor that defines the Radar dielectric factor |K|**2. It is useful in Rayleigh theory to define absorption cross section from its imaginary part

Parameters

eps (complex) – nd array of complex relative dielectric constants

Returns

Rayleigh complex dielectric factor K

K2(eps)[source]

Radar dielectric factor |K|**2

Parameters

eps (complex) – nd array of complex relative dielectric constants

Returns

Radar dielectric factor |K|**2 real
