The influence of the ridge position on the cutoff wavelength of the dominant mode in asymmetric single ridge waveguide is analyzed by finite difference method. 用有限差分方法分析不對稱(chēng)脊波導中脊位置變化時(shí)對主模截止波長(cháng)的影響。
In the case of homogeneous broadening only one mode can normally oscillate. 對于均勻加寬的情況，只有一個(gè)模能正常地振蕩。
The resonant frequency of a quartz crystal is generally determined by the size of the plate combined with the mode in which it vibrates. 石英晶體的諧振頻率通常是由組合振蕩模式之振動(dòng)片尺寸來(lái)決定的。
