nonabsorbing

non- +‎ absorbing

nonabsorbing (comparative more nonabsorbing, superlative most nonabsorbing)

1. That does not absorb (sound, radiation, fluid etc.)
   • 2001, Jill M. Olinger, Peter R. Griffiths, Thorsten Burger, “Theory of Diffuse Reflection in the NIR Region”, in Donald A. Burns, Emil W. Ciurczak, editor, Handbook of Near-Infrared Analysis, page 42:

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

   • 2012, Milan Milosevic, Internal Reflection and ATR Spectroscopy:

     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.

   • 2016, John H. Seinfeld, Spyros N. Pandis, Atmospheric Chemistry and Physics, page 977:

     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.

2. (mathematics) That permits a transition to a different state.
   • 1991, Robert E. Markland, Topics in Management Science, page 553:

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

   • 2015, Carla C. Morris, Robert M. Stark, Finite Mathematics: Models and Applications, page 307:

     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.

   • 2020, Matthew A. Carlton, Jay L. Devore, Probability with STEM Applications, page 453:

     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.
