“…However, it becomes complex when the termination is nonlinear [5]. Macromodeling techniques attempt at solving this problem by building the equivalent circuit of the transmission line, which can then be directly linked to nonlinear SPICE-like circuit simulators [6,7,8,9]. The method in [10] can handle a transmission line above a lossless ground excited by the external electromagnetic fields.…”

Based on the vector fitting and the controlled sources in HSPICE, the delay extraction-based passive compact transmission-line (DEPACT) macromodeling for a transmission line above a lossy ground is presented. Combined with the equivalent sources of the external electromagnetic fields, the equivalent circuits about the scatted voltages and total voltages are proposed. The simulation results are compared with the inverse Fourier transform method and good agreement is obtained. At the same time, using this approach, the transient response for a transmission line above a lossy ground with nonlinear terminations excited by the external electromagnetic fields could be obtained easily and accurately.

“…As we all know, large computational consumption is needed to solve such a problem using full wave analysis. Xie proposed a hybrid FDTD-SPICE method [22] to analyze lossless TLs with nonlinear or time-varying loads illuminated by a non-uniform electromagnetic, in which effective voltage and current sources are obtained first using field-to-TL coupling method after the incident fields to the lines are calculated using FDTD, and then imported into SPICE to deal with the nonlinear loads [23]. Bayram mentioned nonlinear loads in the hybrid S-parameters method used for field-to-TL coupling [24], but again the nonlinear loads had to be handled by HSPICE or ADS.…”

Abstract-An analysis method for electromagnetic field coupling to microstrip line connected with nonlinear components is proposed in this paper. Different from the published work, not only the voltage and current response of the nonlinear component connected to the transmission line (TL) can be obtained, but also the power transmitted from this nonlinear component to the next one at both the fundamental frequency and harmonics can be predicted. The proposed method suitably combines the classical field-to-TL coupling theory and the nonlinear large-signal scattering parameters on the basis of a black box model in frequency-domain. Then this method is experimentally validated by a laboratory system including a microstrip line connected with a simple nonlinear component constituted by the anti-paralleled HSMS-282C Schottky diodes pair welded to a 50 Ω microstrip line. The calculated results using the proposed method show good agreement with the measured data.

“…But the 3D full-wave method requires large number of memories and longer computing time. In recent years, several authors have proposed the hybrid method [12][13][14][15][16], i.e., the co-simulation of combining the full-wave method and commercial simulation software (such as HSPICE and ADS). In these attractive methods, the field coupling effects are analyzed by full-wave technique and incorporated into the simulators for co-simulations.…”

“…In these attractive methods, the field coupling effects are analyzed by full-wave technique and incorporated into the simulators for co-simulations. But [12][13][14] are only suitable for the case of transmission line system, and [15] can only have the frequency analysis.…”

Abstract-This paper presents an extended delay-rational macromodel for electromagnetic interference analysis of mixed signal circuits. Firstly, an S-parameter matrix based delay-rational macromodel of the associated microwave network or system is established. Then, we extend the macromodel to include the external electromagnetic interference effects. The forced waves induced by the excitation fields are computed using full-wave method and treated as additional equivalent sources. Next, the macromodel is modified to embed the additional sources at each corresponding port. Finally, the resulting macromodel is converted into equivalent circuit for circuit analysis with the corresponding linear and non-linear port terminations. Several examples are computed by using the proposed method and the numerical results are compared with those obtained by 3-D FDTD method only. They are all in a good agreement that validate this method.
