The term inal-zone e ffec ts on t he dipole ante nna drive n by a two-wire trans mission line have been re-exam ined. A series inductive cO l'l'ectio n Lg together with other terminal-zone cOl'l'ections is found necessary to redu ce t he meas ured appare nt admi ttance of the a ntenna terminatin g the two-wire line \\'ith the idea l admittance of the dipole a nte nna II-hen drive n by a delta-fun ction generator. The series inductive co rrect ion takes account of t ile abse nce of the ante nna wire in the g'l\p betwee n t he two wires of the transmiss ion line.

الگوریتم جامعی برای مکان یابی خطا در خطوط انتقال دو مداره و چند پایانه ای (بیش از سه پایانه) مبتنی بر داده های PMU
A new PMU-based fault detection/location algorithm for multi-terminal transmission lines is proposed in this paper, which works on the basis of synchronized voltage and current phasors received from PMUs installed in various terminals. The Clark transform (for transposed transmission lines), Eigen-values and eigenvectors theory (for un-transposed ones) are used to decouple 3-phase differential ...
متن کاملUnitarity Corrections to the Proton Structure Functions at the Dipole Picture
We study the dipole picture for the description of deep inelastic scattering, focusing on the structure functions which are driven directly by the gluon distribution. The current theoretical and phenomenological status are properly reviewed. One performs estimates using the effective dipole cross section given by the Glauber-Mueller approach in QCD, which encodes the corrections due to the unit...
متن کامل“Crossed-Field” and “EH” Antennas Including Radiation from the Feed Lines and Reflection from the Earth’s Surface
An ongoing challenge in electrical engineering is the design of antennas whose size is small compared to the broadcast wavelength λ. One difficulty is that the radiation resistance of a small antenna is small compared to that of the typical transmission lines that feed the antenna, so that much of the power in the feed line is reflected off the antenna rather than radiated unless a matching net...
متن کاملCooperative Fluorescence from a Strongly Driven Dilute Cloud of Atoms
We investigate cooperative fluorescence in a dilute cloud of strongly driven two-level emitters. Starting from the Heisenberg equations of motion, we compute the first-order scattering corrections to the saturation of the excited-state population and to the resonance-fluorescence spectrum, which both require going beyond the state-of-the-art linear-optics approach to describe collective phenome...
