The program performs computation of propagation constants for electromagnetic wave in dispersive media formed of homogeneous monodispersed spherical particles. The computations are carried out in so-called quasi-crystalline approximation (QCA) proposed by Lax.

the wave number of the dispersive media in the QCA normalized to the wave number of the background medium,

the wave number of the dispersive media in the independent scattering approximation (INA) normalized to the wave number of the background medium,

extinction coefficient in the QCA normalized to the wave number of the background medium,

extinction coefficient in the INA normalized to the wave number of the background medium,

extinction coefficient in the QCA normalized to the extinction coefficient in the INA.
