Numerical Analysis of Crosstalk Effects of Uniform Interconnect Lines Using theta-method

The significant advancements in electronic and communication systems necessitate the development of systems capable of processing data rapidly within short timeframes. Therefore, it is crucial to enhance every element of these circuits, with particular emphasis on interconnects as they play an essential role in these systems. Modularization of their characteristics is a necessary step in these processes to develop these systems. As a result, numerical methods are employed to achieve effective modeling with high accuracy and stability. In this paper, the theta-method has been developed for the analysis of crosstalk effect in three coupled interconnects. The analysis has been conducted both in the absence and presence of an electromagnetic field that affects the interconnects. The conventional Finite Difference Time Domain method (FDTD) has been employed with PSPICE for comparison and validation. The results achieved in this work using the proposed method have shown higher accuracy and stability compared to both conventional method and PSPICE.
