In this paper, the
forbidden band structure in which able to propagate certain frequencies and
transmission properties with respect to periodicity condition are investigated
in one dimension photonic crystal has a dielectric constant which change
periodic. However, the dispersion properties with respect to refractive indexes
belong to certain crystal are used in calculation of n_eff refractive
indexes of guided modes.

Bu çalışmada, dielektrik sabiti periyodik olarak
değişen tek boyutlu bir fotonik kristalde belli frekansların iletimine izin
veren yasaklı band yapısı ve periyodiklik koşuluna bağlı olarak iletim

bağlı olarak
incelenen dağılım özellikleri, kılavuzlanan modların n_eff etkin
indislerinin hesaplanmasında kullanılmıştır.
