| 摘 要： | 以有机高分子磁性材料作为金属壁谐振腔的填充材料，根据腔体内的场结构，分析材料的相对磁导率和介质损耗对谐振腔的品质因数的影响．分析表明，在介质损耗相同的情况下，谐振腔的品质因数随相对磁导率呈增加趋势，且介质损耗越小，增加趋势越明显．

| Abstract: | The influences of the relative permeability and the dielectric loss of this material on the quality factor of a metal resonance cavity filled with organic magnetic materialwere analyzed by taking the characteristic of electromagnetic fields inside the cavity. The results show that the quality factor increases with an increase in relative permeability with the same dielectric loss, and the less the dielectric loss is, the more obviously the quality factor will increase. |
