The absorption of normally incident light by axially excited slabs of dielectric thin‐film helicoidal bianisotropic media (TFHBMs) is shown to be polarization dependent, and the circular Bragg phenomenon turns out to saturate as the slab thickness increases beyond a certain value. A specific feature of absorption in the Bragg regime is reflected in the transmittances, which may be monitored for the automated production of TFHBMs. ©1999 John Wiley & Sons, Inc.
