提出一种新型的物料水分测量传感器——缝隙阵分裂式圆柱谐振腔.对带缝隙阵的分裂式圆柱谐振腔进行了大量分析与研究,验证了缝隙阵分列式圆柱谐振腔的可行性.通过对缝隙阵分裂式圆柱谐振腔和非缝隙阵分裂式圆柱谐振腔的比较分析,证明缝隙阵结构可使整个谐振腔的磁场分布得更均匀,可以避免因为物料局部水分不均而产生误报,从而使得利用缝隙阵分裂式圆柱谐振腔测量测物料水分的测量值更准确.而且缝隙阵分裂式圆柱谐振腔的驻波比更好,功率损耗更小,节约能源;缝隙阵结构能保证谐振腔谐振在TE011模式,确保测量更精确.

英文摘要：

This paper presented a new sensor for material moisture measurement -the split cylinder resonator with slot array. The resonator with slot array was simulated and analyzed; also the feasibility was verified. The advantages of the new structure were evaluated by com- paring between resonator with slot array and no - slot. It could be seen that the magnetic field distribution of the resonator with slot array was more uniform than that of resonator with no - slot resonator, avoiding errors caused by the material＇ s local uneven moisture, making moisture measurement value more accurate than other sensors. With the slot array, VSWR of the split cylinder resonator became better, the transmission loss got smaller and the power was reduced. Slot array structure ensured the cavity resonant work in the situation of the TE011 mode to get a more accurate measurement value.
