Matrix Pencil method

Abstract

"Full-wave time-domain algorithms are widely used in the analysis and design of electromagnetic systems. Many of these are often characterized by long time responses, and accordingly the simulation algorithms have to employ many time steps in order to obtain a complete description of those responses. However, the time-consuming computational effort can be avoided, if the characteristic parameters are extracted from the response truncated in advance and then used to reconstruct the waveform at each time instant. An optimized version of the Matrix Pencil method is presented in this thesis. A successful application of this method relies on the choice of the optimum number of poles M, and the pencil parameter L, respectively. Therefore, once these two quantities are properly chosen, a good reconstruction is only a function of the number of samples recorded. The Optimized Matrix Pencil method can be iteratively applied to the data given by a time domain simulation algorithm, and a convergence criterion can be employed to decide whether the data samples recorded are sufficient, and a good reconstruction can be achieved.

Some closed-form expressions are also presented in this thesis, regarding the evaluation of surface-mount component parasitic inductance. In fact, the correct model of a circuit, when routed on a board, helps to find the best solution from the signal integrity point of view. The closed-form expressions are calculated and compared to some measurements for capacitor pads on 4-layer boards in particular. fu fact, capacitors are among the most important and widely used surface-mount components and the parasitic inductance limits the benefits of them"--Abstract, page iii.
