摘要

本文通过在复平面上求解所选模式的特征方程，计算了圆柱介质谐振器的辐射品质因子。在所有情况下，这个Q因子对于实际应用来说都太低了。因此，为了防止辐射造成的损失，我们将介电谐振器包裹在金属圆柱形屏蔽中。对于这种几何结构，计算了屏蔽谐振器的空载质量因数。

Q Factors of Free and Shielded Cylindrical Dielectric Resonators

In this paper, the radiation quality factor of cylindrical dielectric resonators has been evaluated by solving the characteristic equation of the chosen mode in the complex plane. In all cases this Q factor is too low for practical applications. So in order to prevent the losses by radiation we enclose the dielectric resonator in a metallic cylindrical shield. For such a geometry the unloaded quality factor of the shielded resonator has been calculated.
