The High-Mode-Merging Technique for Dielectric Waveguide

The mode-matching method and transverse resonance technique for dielectric waveguide was developed in 60s-70s last century. After that, only few attentions were paid. But it may be an effective method. According to the strict mode-matching method of the solving electromagnetic field, a derived method-high-mode-merging method is approached, than a kind of the equivalent network can be got. The network not only expresses the characteristic of the dominant mode mainly but also considers the influence of high modes if they are excited. Thus it guarantees strictness of original theory and simplifies the calculation consumedly.
