摘要。我们研究是否需要修改传统的传输线理论，如果传输线被认为是在一个空腔而不是在自由空间。我们的分析基于耦合波克林顿方程，该方程可以简化为天线模式和传输线模式的积分方程。在传统传输线理论的通常假设下，这些模式在腔内近似解耦。因此，空腔特性将主要影响天线模式，而不是传输线模式。
Abstract. We investigate whether or not conventional transmission line theory needs to be modified if transmission lines are considered that are located in a cavity rather than in free space. Our analysis is based on coupled Pocklington's equations that can be reduced to integral equations for the antenna mode and the transmission line mode. Under the usual assumptions of conventional transmission line theory these modes do approximately decouple within a cavity. As a result, cavity properties will primarily influence the antenna mode but not the transmission line mode.
