RT Journal Article ID 4b3d188c6337dd64 A1 Sulima, A. T1 Brag Reflector with an Arbitrary Type of Refractive Index Modulation JF Telecommunications and Radio Engineering JO TRE YR 2001 FD 2001-04-01 VO 55 IS 4 OP 8 AB A new approach to the problem of parameters calculation of a Brag reflector with an arbitrary type of refractive index modulation on perturbed part of media is proposed. The method allows obtaining a good approximation to the exact solution provided that magnitude of the refractive index modulation is small and reflectors length is large.
