The global theory of transmission line networks with nonconservative junction conditions is developed from a spectral theoretic viewpoint. The rather general junction conditions lead to spectral problems for nonnormal operators. The theory of analytic functions which are almost periodic in a strip is used to establish the existence of an infinite sequence of eigenvalues and the completeness of ...

Timeand frequency-domain theory of multiwire magnetic transmission lines is presented for the first time. The familiar theory of electric multiconductor transmission lines (MTL) is based on the manipulation of two matrices, the longitudinal impedance and the transverse admittance. However, for magnetic MTLs, the key matrices are the transverse impedance and the longitudinal admittance. It is sh...

A new generalized transmission-line theory is presented to treat multiconductor as well as antenna systems. Maxwell’s equations are cast into the form of classical telegrapher’s equations. Two quite different examples are calculated to illustrate the wide use of this theory.

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...

modeling and simulation of communication circuits at high frequency are important challenges ahead in the design and construction of these circuits. knowing the fact that the lumped element model is not valid at high frequency, distributed analysis is presented based on active and passive transmission lines theory. in this paper, a lossy transmission line model of traveling wave switch (twsw) i...
