【摘要】 用HFSS10.0对混响室进行仿真,研究了搅拌器的夹角对场均匀性的影响。首先阐述了混响室的特点及其场均匀性校准的原理和方法,然后根据实际混响室的尺寸,用HFSS10.0进行建模,通过仿真得出搅拌器在不同夹角情况下的场均匀性。最后根据仿真结果,对混响室的场均匀性进行测量,验证了合理的设计搅拌器会改善混响室的场均匀性,降低最低可用频率。更多还原

【Abstract】 We will discuss the effects of the angle between the oars on the performance of the reverberation chamber(RC) by simulation with HFSS10.0.Firstly,this paper described the characteristic of reverberation chamber,the principle and method of field uniformity calibration.Then according the real RC’s size,we set up model with HFSS10.0,and did simulation to get the field uniformity at different angles between the oars.At last,we carried out the measurement on the basis of the simulation result.It proved that proper design of stir will improve the field uniformity and lower the minimum useable frequency.更多还原
