“…5 Results computed the per-unit-length matrices of various structures, for which there exist published original and obtained results. Firstly, we compared results for a simple case of 2 coupled strips on a substrate [26] shown in Table 2. However, we consider the cases of side dielectric walls becoming closer to side strip edges and the similar cases without side dielectric walls ( Table 2).…”

In this paper we consider the complexity problem in electronics production process. Particularly, we investigate the ways to reduce sensitivity of transmission line characteristics to their parameter variations. The reduction is shown for the per-unit-length delay and characteristic impedance of several modifications of microstrip transmission lines. It can be obtained by means of making an optimal choice of parameter values, enabling proper electric field redistribution in the air and the substrate. To achieve this aim we used an effective simulation technique and software tools. Taken together, for the first time, they have allowed formulating general approach which is relevant to solve a wide range of similar tasks.

96УДК 621.396.41 Р.Р. АхуновАнализ полосковых структур радиоэлектронных устройств с уменьшенными вычислительными затратами Приведены результаты вычисления значений погонных коэффициентов электростатической и электромагнит-ной индукции для связанной микрополосковой линии. Результаты получены с использованием алгоритмов ре-шения систем линейных алгебраических уравнений итерационным методом с предобусловливанием. Для пре-добусловливания использован формат хранения разреженных матриц, что позволило уменьшить вычислитель-ные затраты. Приведено сравнение полученных результатов с результатами других авторов. Сравнение показа-ло согласованность результатов. Ключевые слова: полосковые структуры, метод моментов, система линейных алгебраических уравнений, ите-рационный метод, предобусловливание, погонная матрица.

“…If d ( w ) and c"(w) are known for the dielectric material(s) in the transmission line system, then G(w) and C ( w ) may be calculated from the cross-sectional transmssion line geometry using a boundary-element solution for the surface charge densities [13]. Since €(U), as formulated above, satisfies the Kronig-Kramers equations, then Y ( w ) will as well.…”

This paper presents a method for the time-domaan simulation of multiconductor transmission lines with frequency-dependent conductor (skin effect) and dielectric losses. The method is based on a traveling wave solution of the transmission line equations in the frequency domain, with time-domain simulation achieved by convolving the transmission line terminal voltages with describing time-domain input and tmnsfer impulse responses derived from the frequencydomain solution. Attention must be given to careful formulation of the frequency-dependent conductor and dielectric losses to assure causality in the transmission line responses. The ezcessive numerical burden of discrete-time convolution is avoided by approzimating the tmnsmission line responses with ezponential series, which may be convolved recursively, making the tmnsmission line solution feasible and practical for large simulations. An implementation of the solution algorithm an the circuit simulation program SPICE is described, and sample results for a microstrip system presented.
