提出了一种用任意集总元件电路驱动和终止Holland-Simpson细线模型的方法。该方法使用的事实是，这些细线模型的结果在修改电报员的方程，和接口传输线和集总元件电路是简单的。电路/导线连接处的细线电压和电流可以用电路节点电压和分支电流来表示，从而使电路解可以作为细线系统的边界条件。在这项工作中，我们提供的电路/电线接口的条件和联合收割机电路与Edelvik的荷兰-辛普森模型，允许细电线任意取向内的非结构化网格。Edelvik的工作，以前实施的有限差分和有限元时域求解器制定的有限体积法。电路驱动的细线天线的数值和实验结果提供了验证该方法。
A method for driving and terminating Holland-Simpson based thin-wire models by arbitrary lumped-element circuits is proposed. The approach uses the fact that these thin-wire models result in modified Telegrapher's equations, and interfacing transmission lines and lumped-element circuits is straightforward. The thin-wire voltage and current at a circuit/wire junction can be written in terms of circuit nodal voltages and branch currents, permitting the circuit solution to act as a boundary condition for the thin-wire system. In this work, we provide the circuit/wire interfacing conditions and combine circuits with Edelvik's Holland-Simpson model that permits thin-wires to be arbitrarily oriented within an unstructured mesh. Edelvik's work, previously implemented for finite-difference and finite-element time-domain solvers is formulated for the finite-volume method. Numerical and experimental results for circuit-driven thin-wire antennas are provided to validate the method.
