    In ray tracing, it is standard practice to consider solely the real part of any medium's refractive index for determining the changes in a ray's direction at the interface between two media. Any absorption is accounted for by reducing the intensity or weight of the ray in accordance with its propagation distance.

    With the generalized group velocity vg= Re (∂ω/∂k) for media with moderate absorption, derived in a previous paper, the Hamilton equations for group propagation in non-absorbing media are generalized to include moderate absorption. They contain directional derivatives not only in the direction of v but also in the direction of Im (∂ω/∂k).

    We conclude with recommendations for ray tracing involving absorbing media. If polarization information is needed, it is essential to use the more rigorous method for, say, κ / n > 0.01 . For unpolarized ray tracing, the standard approach works well when κ / n < 0.07 . These guidelines are rough estimates for obtaining results within around 1 ...

    The ray tracing technique in absorbing, isotropic or anisotropic stratified media, and particularly in plane-stratified media is discussed. There are two approaches. One is to construct the complex refractive index vector and use the principle of stationary phase. The other is to impose a spatial beam signal on the medium having, e.g., a Gaussian profile and to find the peak of a …
