摘要：

介绍了2.45GHz频率高功率微波陶瓷窗的结构及对结构的优化。结构优化包括对结构尺寸和水冷结构的水流率取值这两方面。当陶瓷片厚度为4.4mm、圆波导长度为52.3mm时，微波性能达到最优。当水冷结构的水流率为0.4t×h^-1时，效果最理想，此时陶瓷片的最大应力值远远小于陶瓷片本身的抗拉强度。优化后的陶瓷窗经过多轮实验的考验，没有出现破裂等问题。

关键词: 陶瓷窗, 结构尺寸优化, 水流率优化

Abstract:

The structure and its optimization of 2.45GHz high power microwave ceramic window are introduced in this paper. The structure optimization includes optimization of structure dimensions and coolant flowing rate. The microwave properties are sufficient when the thickness of ceramic disk is 4.4mm and the length of cylindrical waveguide is 52.3mm. The maximum thermal stress on the ceramic disk is far less than the limitation that ceramic disk could sustainable stress when the coolant flowing rate is 0.4t×h^-1 . Optimized ceramic window did not appear crack problem after several runs of experiments.

Key words: Ceramic window, Optimization of structure dimensions, Optimization of coolant flow
