Waveguide is a kind of low loss transmission line . energy can be coupled by slots in the waveguide ’ s walls 在波导上开缝隙就能将能量从波导中通过缝隙耦合出去。
2.
The high efficient algorithm base on finite - element for the character of body with open cavities " scattering and coupling has been studied in this dissertation 本文主要研究了用有限元方法分析计算腔体目标和含腔目标的的电磁散射和缝隙耦合特性的高效算法。
