explicit solution 在 数学 分类中 的(2)

The process of drawing the dispersive curve is shown in fig。3。 Fig。4 shows the TE mode dispersive characteristics got from the graphical method in this paper。 The eigenvalue equation of the TM mode of one dimensional thin-film optical waveguide can also be solved by the method similar to that of the TE mode。 The results are given in this paper, too。explicit solution In conclusion, the graphical method shows itself as a useful auxiliary means of interpreting the thin-film optical waveguide。 Through the analysis of the geometrical relation, the author has also obtained the explicit solution of the cut-off wavelength of the TE and TM modes as shown by Eq。(8b) and (14)。
