  The effect of anisotropy on defect mode peculiarities in cholesteric liquid
crystals is investigated. The problem is solved by Ambartsumians layer addition
modified method. Two cases are considered. In the first case, it is assumed
that the defect layer is not absorbing and the effect of refraction anisotropy
on the reflection, relative photonic density of states and the total field
intensity aroused in the defect layer are studied . In the second case, defect
layer is assumed to be isotropic for refraction and anisotropic for absorption,
and the influence of defect layer absorption anisotropy on reflection,
absorption, relative photonic density of states and the total field intensity
aroused in the defect layer are investigated.
