我们表明，光子带隙（PBG）波导的限制模式的属性可以计算具有良好的精度，通过将其替换为一个有效的波纹波导，仅代表在中间板附近的结构。这种替换有助于光子带隙波导的设计以及不同波导之间耦合的理解和分析。
We show that the properties of the confined modes of a photonic band-gap (PBG) waveguide can be calculated with good accuracy by replacing it with an effective corrugated waveguide that represents only the structure in the vicinity of the middle slab. Such a replacement is helpful in the design of the PBG waveguides as well as in the understanding and analysis of the coupling of different waveguides.
