Micro-strip line crosstalk based on multi-resolution time domain method

The absorbing boundary condition can affect computational accuracy of the multi-resolution time domain(MRTD).The paper presents the anisotropic perfectly matched layer(APML) absorbing boundary condition based on CDF(2,6) compactly supported scaling function.The MRTD operates on micro-strip line crosstalk analysis,lumped resistance and impedance voltage source elements are simulated for any scaling function.The proposed algorithm is used to analyze the crosstalk between two parallel micro-strip lines on the printed circuit board.Compared with the conventional finite difference time domain(FDTD) method,experiments demonstrate that the MRTD based on CDF(2,6) scaling function only needs half the cells,computational speed can be improved by 3 times,and the utilization of memory requirement and execution time are less.
