The FDTD method is presented to analyze the crosstalk characterization of three dimensional multiconductor interconnect structures.First,Marple method of AR model,parameter extraction and correction technique are used to reduce the computing time and optimize the solution;Then,the super absorbing boundary is applied to reduce the number of mesh nodes or memory.The effective dielectric constant and S parameters are calculated.For some common structures,the results are in good agreement with that reported in other papers,and the crosstalk of some multi conductor structures is analyzed.
