“…At present, some efficient numerical methods have be proposed to solve the coupling problems of ambient wave to the transmission lines (TLs), such as BLT Equation, SPICE method, and FDTD‐TL method, and so on. The aim of these methods is to obtain the transient responses on the TLs in the absence of the lines.…”

Due to the numerical methods used for the coupling analysis of the shielded cavity with penetrated wire excited by ambient wave are lack, an efficient time domain hybrid method is presented in this article, which consists of thin wire finite difference time domain (FDTD) method and hybrid FDTD and transmission line equations method (called FDTD‐TL method). In this method, the penetrated wire is decomposed into external and internal transmission lines according to the enclosure structure of the shielded cavity firstly. Then the thin wire FDTD method is applied to calculate the currents on the external transmission line, which are enforced as the boundary of the internal transmission line naturally. Meanwhile the FDTD‐TL method is used to build the coupling model of ambient wave to the internal transmission line to obtain the voltage and current responses on the terminal load of internal line. This method has one prominent advantage is that it can realize the cooperative calculations of electromagnetic field radiation and the coupling responses on the penetrated wire. Finally, two numerical simulations of ambient wave to one shielded cavity with penetrated wire in the free space and shielded cavity are utilized to verify the accuracy and efficiency of this presented method by comparing with the electromagnetic software CST.

“…A complex electronic system can be decomposed into numerous subsystems based on EMT, thus decreasing the difficulty of EMC problems. In recent years, more and more researchers have studied EM coupling with TL, printed circuit board, or other objects in the enclosure on the combination of EMT and other methods [2, [21][22][23]. However, the line is placed in a single enclosure [22], and the shielding structure is illuminated by a single source [2, [21][22][23].…”

Few investigations concentrate on the EM coupling with the TL in different enclosures against multiple excitation sources, and the increase in numbers and varieties of the enclosures and sources complicate the EM interaction.…”

“…At present, several fieldto-cable coupling methods have been proposed, such as Baum-Liu-Tesche (BLT) equation, simulation program with integrated circuit emphasis (SPICE) methods, and FDTD-TL method. BLT equation [4][5][6][7][8] is a frequency domain method, which can only obtain the transient responses on the terminal loads of the cables, and the loads should be linear and time invariant. The SPICE methods [9][10][11][12][13][14] can be well applied to the coupling analysis of nonuniform electromagnetic fields or plane wave to the cables on the ground.…”

Abstract-This paper presents an efficient hybrid method consisting of finite-difference time-domain (FDTD) method, transmission line (TL) equations, and a fast calculation method for excitation fields, which can be applied to the coupling analysis of the shielded cable on the ground excited by plane wave rapidly. It can avoid modeling the infinite ground and the structure of the shielded cable directly. In this hybrid method, the shielded cable is decomposed into external and internal transmission line models, and the corresponding TL equations for the external and internal TL models are established necessarily. Then the FDTD method is utilized to solve the TL equations to obtain the transient responses on the shielding layer and core wires of the cable. A numerous examination of the coupling of coaxial cable exhibits that this hybrid method has very high accuracy and efficiency compared with the SPICE method. Finally, the methods of effective shielding protection of the cable have been proposed by analyzing the influences of the grounding states of the shielding layer, the electromagnetic parameters of the ground and the heights of the cable on the transient responses of the cable.
