Main Program

qcamie.m calculates the effective propagation constant in a dense medium consisting of Mie scatterers using the quasi-crystalline approximation in the T-matrix formulation. The Mie scatterers are distributed according to the Percus-Yevick pair distribution function.

Example

The figures below are generated with the following parameters:

freq=37 GHz, epsilon_p=3.2375+i0.18, f=0.2, ka=linspace(0.01,2.5,40), n_max=4

Note that the (normalized) phase velocity is k/real(K_eff) while the loss tangent is 2*imag(K_eff)/real(K_eff).
