A wavelet approach to the analysis of nonuniform high-speed interconnects with frequency dependent parameters is presented in this paper. The nonuniform interconnects are modeled by the use of nonuniform multiconductor transmission line equations in the frequency domain. Two different methods are proposed here (differential and integral formulation): in both of them the space variable is expand...

A. Gholami and M. Mirzai,

Overhead transmission lines are influenced by different factors which are mostly electrical and mechanical. These factors can cause problems for lines, distortions in network and outage of line. In designing transmission lines mechanical properties are evaluated after selecting a suitable conductor and clearance with regard to electrical properties. In lines designing, an important mechanical p...

Modern transportation systems, such as aircraft, are increasingly replacing metal body parts for composite materials, carbon-fiber reinforced plastics. Despite the multiple advantages in terms of weight, size, and fuel consumption, this trend is posing a challenge protection cables against electromagnetic interference. Early risk assessment optimization cable design modern aircraft require reli...

Conventional fault location methods using voltages and currents of one terminal are not applicable to multiterminal transmission lines. So far some techniques have been presented to solve fault location problem for multi-terminal transmission lines. In these methods, lumped or distributed frequency domain models of transmission lines have been used. In multi terminal lines, faulty section shoul...

a novel ultra wideband microstrip bandpass filter using radial stub loaded resonator and interdigital coupled lines is presented in this paper. the radial stub loaded resonator and decagonal patch form a resonator named m to create tuneable multiple notches in the passband for suppression wlan interference. to realize sharp roll-off, two adjustable transmission nulls are located at the lower an...

با پیشرفت تکنولوژی و افزایش فرکانس و کاهش ابعاد در بردهای الکترونیکی، تاثیرگذاری و تاثیرپذیری خطوط انتقال درون برد بر هم افزایش یافته است. برای اطلاع از میزان این تاثیر نیاز به محاسبه همشنوایی بین خطوط جدی می شود. همچنین برای اطلاع یافتن از اینکه برد حاصل استانداردهای emc را بر آورده می کند، باید میزان ولتاژ و جریان القایی در انتهای خطوط هنگامی که این برددر حضور میدان الکترومغناطیس خارجی قرار گ...

Matrix equations (AX = B,XC = D) is a class of important matrix equations. The problem of the solution of the matrix equations (AX = B,XC = D) arise in engineering and in some special matrix inverse problems [1-3]. Many authors have been devoted to the study of this problem, and a series of useful results have been obtained. For example, Mitra [4] gave the common solution of minimum possible ra...
