翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Radiation mode ： ウィキペディア英語版 Radiation mode For an optical fiber or waveguide, a radiation mode or unbound mode is a mode which is not confined by the fiber core. Such a mode has fields that are transversely oscillatory everywhere external to the waveguide, and exists even at the limit of zero wavelength. Specifically, a radiation mode is one for which :$\backslash beta\; =\; \backslash sqrt$ where ''β'' is the imaginary part of the axial propagation constant, integer ''l'' is the azimuthal index of the mode, ''n''(''r'') is the refractive index at radius ''r'', ''a'' is the core radius, and ''k'' is the free-space wave number, ''k'' = 2π/''λ'', where ''λ'' is the wavelength. Radiation modes correspond to refracted rays in the terminology of geometric optics. ==See also== *Guided ray *Numerical aperture 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Radiation mode」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
