论文摘要
空腔的共振模式的外部Q因子代表了这种谐振模式与波导耦合到腔的传输模式之间的电磁耦合的强度。在本文中，我们得出了公式，以明确地给出腔的外部Q，并通过电容和电感耦合结合波导。该推导基于使用反射系数来估计耦合强度的经典方法。尽管目前通过三维计算机模拟评估了外部Q，但这些公式对于在腔设计的初始阶段进行投机可能很有用。
The external-Q factor of a resonant mode of a cavity represents the strength of the electromagnetic coupling between this resonant mode and the transmission mode of a waveguide coupled to the cavity. In this paper, we derive formulas to explicitly give the external Q of the cavities coupled with the waveguide through capacitive and inductive coupling. The derivation is based on the classical method that uses the reflection coefficient to estimate the coupling strength. Although the external Q is evaluated via three-dimensional computer simulations currently, these formulas may be useful for making speculations in the initial stages of cavity design.
