In this paper,the macro model of interconnects with frequency-dependent parameters on the back-plane is presented by using ABCD matrix method.

Methods Patients were evaluated according to ABCD criteria and ABCD2 criteria.

Basing on time domain ABCD matrix formalism and giving more consideration on the influences of optical fiber dispersion and optical fiber nonlinearity,it analyzed the laser′s characteristics of actively mode locked fiber laser,and compared the theoretical analysis results with experimental ones.

The propagation rule through ball lens based on the ABCD matrix is presented.

The ABCD matrix of transmission lines is obtained by the rungekutta iteration, then the ABCD matrix is used to obtain the solution in the laplacedomain, finally the timedomain response is obtained through the numerical inversion of the laplace transform, so that the traditional NILT method is able to analyze the nonuniform transmission lines, at the same time, it is efficient and accurat

The new model calculates the "equivalent ABCD matrix" of the interconnect tree for approximations of transfer functions of the interconnect tree, and then derives the closed-form solution for the 50% delay by means of second-order moment matching and curve fitting.
