this paper proposes an optimal transmission expansion planning (tep) which is based on determining share of each line in merchandizing surplus (ms) of system, determining by independent system operator (iso). the more share of a line in ms of system denotes the priority of a line for expansion. the procedure of determining ms of each line in a power system is based on determining the ms share o...

Effects of 3-D surface roughness on the propagation constant of transverse electromagnetic transmission lines are calculated using finite-element method software by solving for the fields inside conductors. The modeling is validated by comparison with available literature results for the special case of 2-D surface roughness and by simulations using the finite-integration technique. Results for...

A fast stripline beam kicker is used to dynamically switch a high current electron beam between two beamlines. The transverse dipole impedance of a stripline beam kicker has been previously determined from a simple transmission line model of the structure [1]. This model did not include effects due to the long axial slots along the structure as well as the cavities and coaxial feed transition s...

آنتن های زیادی با سطح مقطع استوانه ای وجود دارند که در کنار یا روی آنها تعدادی عنصر تابنده با طول محدود وجود دارند. این ساختارهای تقریبا استوانه ای را می توان با روش ‏‏‎s2ds(spectrum of two dimensional solutions)‎‏ تحلیل نمود. به این ترتیب که با استفاده از تبدیل فوریه نسبت به محور استوانه (محور ‏‎z‎‏ )، مسئله الکترومغناطیس سه بعدی اینگونه آنتن ها را می توان بصورت عکس مسائل دو بعدی با تغییرات ها...

This paper deals with the problem of estimating the losses in highly-conducting wires, in a frequency range where the transverse dimension is comparable to the signal wavelength. In this case the standard transmission line model fails since it cannot predict high-frequency effects like radiation in the transverse plane. Here we use a recently proposed enhanced transmission line model which, alt...

Concerns regarding possible transverse instabilities in RHIC and the SNS pointed to the need for measurements of the transverse coupling impedance of ring components. The impedance of the RHIC injection and abort kicker was measured using the conventional method based on the S21 forward transmission coefficient. A commercial 450 Ω twin-wire Lecher line were used and the data was interpreted via...

In this paper, a microstrip transmission line combined with a new U-headed dumb-bell defected ground structure (DGS) is investigated. The proposed DGS of two U-shape slots connected by a thin transverse slot is placed in the ground plane of a microstrip line. A finite cutoff frequency and attenuation pole is observed and thus, the equivalent circuit of the DGS unit can be represented by a paral...
