A new method to predict the crosstalk of multiconductor transmission lines

Crosstalk in multiconductor transmission lines is predicted by using a method of combining the method of moments with finite-difference time domain (FDTD) method. To evaluate the lossy skin-effect lines, quadrature formulae and recursive convolution are used to get accurate results. The modified MTL equations are solved by the FDTD method plus the terminal conditions. Harmonic basis functions and point matching are applied to obtain the capacitance and inductance matrices of transmission lines above a perfect ground plane.
