SD Prijmenko ,ena.lp.edu.ua
Abstract Excitation of a linear impedance antenna is considered in a unlimited circular
waveguide. The antenna is located in the waveguide axis and is excited by the relativistic
point charge scattered at the antenna end-wall. The electric current distribution and the

Abstract This paper demonstrates the application of a new kind of conical wave-objects to
the computation of fields radiated by circular apertures. The radiation integral is transformed
into a summation of complex wave-objects by means of the Fourier series expansion and

D Marcuse ,BELL SYSTEM TECHNICAL JOURNAL, 1977 ,alcatel-lucent.com
At Bell Laboratories, he has been engaged in studies of circular electric waveguides and
work on gaseous masers. He spent one year (1966-1967) on leave of absence from Bell
Laboratories at the University of Utah. He is presently working on the transmission aspect 

 Prime-focus circular waveguide feed with septum polarization transformer
free download

R Galuscak–OM6AA ,2007 ,ok2kkw.com
Dish antenna feeds employing septum polarization transformers, which transform linear
polarization to circular polarization (CP), have now successfully proliferated throughout the
EME community after facing some initial skepticism. Their success is due, in part, to

TY Alekhina ,accelconf.web.cern.ch
Abstract We investigate the field of a small bunch crossing a boundary between two
dielectrics in a circular waveguide. It includes a forced field and a free one. The forced

free download

J Mazur, J Popik, S Haq , ’96 Book of , 1996 ,proceedings.metamorphose-vi.org
Isotropic chiral media have raised considerable interest in recent years because of their

AP Orfanidis, GA Kyriacou ,ursiweb.intec.ugent.be
ABSTRACT The resonant behaviour of multiple offset coaxial irises in a circular waveguide
is exploited in this paper. As the single iris can be used in the design of band-pass filters,
multiple irises on the same diaphragm can be used for the design of multiple pass-bands.
