The Maxwell curl postulates have been analyzed for propagation in the
vertical microstructurally significant plane of a periodically bent ne
matic (PBN) medium. The ordinary modes are unaffected by the anisotrop
y and the periodic inhomogeneity of the PBN medium, but the extraordin
ary modes are. Simple expressions, applicable for small anistropy para
meters, have been found. (C) 1996 John Wiley & Sons, Inc.
