Nonabsorbing

Equation 2 applies only to the case of a dielectric nonabsorbing particle and unpolarized incident radiation.

Another simple, but practically important, case is one of the nonabsorbing film of thickness d₁ on the absorbing film of thickness d₂ over a nonabsorbing substrate.

The aerosol layer scattering model can be simplified if a nonabsorbing aerosol, that is, ω = 1, is considered and account is taken of the fact that the optical depth for most tropospheric conditions is usually about 0.1 or smaller, thereby allowing one to assume τ « 1.

To interprest the results given by the fundamental matrix, recall that the nonabsorbing states are states 3 and 4.

A matrix C where C = NR determines the probability that the chain will enter a particular absorbing state having begun in a given nonabsorbing state.

Starting in a nonabsorbing state i, the chain will eventually be absorbed into absorbing state a if either (1) the chain transitions immediately into ''a, or (2) the chain transitions into any nonabsorbing state and then eventually is absorbed into state a.
