“…(20)- (23) Figure 6 shows the effective dielectric constants calculated for the coupled modes 1, 2, and 3 as functions of frequency. It is seen that the results are in very good agreement with those [10] obtained by the spectral domain method for the coupled three lines. The characteristic mode impedances Z c, 11 to Z c,33 calculated using the total power definition are shown in Fig.…”

“…The characteristic mode impedances Z c, 11 to Z c,33 calculated using the total power definition are shown in Fig. 7 and compared with the values of [10]. A good agreement between both results is observed except for Z c,11 in the high frequency region.…”

“…To verify the proposed theory, two nonidentical coupled lines and three nonidentical coupled lines in a single plane, and two identical coupled lines in dual planes are chosen as models of the coupled-mode analysis. The numerical results for the mode propagation constants and characteristic mode impedances are compared with those [2,[7][8][9][10] obtained by the direct numerical solution method for the coupled-lines. It is shown that both results are in good agreement.…”

“…Full wave analysis has been done to analyze the dispersion characteristic of multi-conductor lines at higher frequencies for wideband application [1]. It is very well known that spectral domain technique has received considerable attention in last decade for a solution of printed circuit problems [1]. The numerical technique used in this paper to compute the normal mode parameters of four and five-coupled microstrip is full wave modal analysis [3].…”

In this paper a full wave modal analysis is performed on four symmetric and asymmetric parallel-coupled microstrip lines and symmetric five-coupled microstrip lines in suspended substrates structures. The numerical procedure based on the modal analysis, is formulated to compute all the frequency-dependent normal mode parameters of four coupled microstrip lines structures. These parameters include phase constant, modal impedances and the dielectric losses of the coupled four lines for all four propagating modes. In addition, attempts have also been made to compute the propagation constant of various propagating modes of five-coupled microstrip lines of equal width and spacing in microstrip lines structure as well as in suspended substrate structure.

SUMMARYCross-talk and pulse distortion in high-speed digital circuits have long been major design considerations. With the present trend towards increased speed and packing density the commonly used TEM approximation is no longer capable of producing sufficiently accurate results. In this contribution, the finite-difference timedomain technique incorporating a novel means of launching the pulses is used to provide a rigorous threedimensional simulation of cross-talk on high-speed digital circuits. This includes the often-neglected effects of higher-order modes and surface waves. Results are presented for pulses propagating along a single track and for coupling between two and three tracks using square, gaussian and raised cosine pulse excitation functions. The results are shown to be in good agreement with other rigorous analyses.
