The proposed geometry is a basic model of the Baltic HVDC submarine power cable measurement\, which was done recently in Sweden. Th e analysis is carried out rigorously by applying direct Fourier transform and reducing the problem into the solution of a modified Wiener-Hopf equat ion of the second type. The solution for the field terms are determined in terms of infinite number of unknown coefficients which satisfy an infinit e set of linear algebraic equations. These unknown coefficients are solved numerically and the effect of area ratio on the reflection coefficient is determined.\n\nBio: Gökhan Çınar received BS and MS degrees in electro nics and telecommunication engineering from Istanbul Technical University in 1998 and 2001\, respectively. He received his Ph.D. degree in electroni cs engineering from Gebze Institute of Technology in 2004. He held the ass istant and associate professorship positions at Gebze Institute of Technol ogy between 2004 and 2015. He started working at Electrical and Electronic s Engineering department of Eskişehir Osmangazi University in 2015 where he was entitled as a full professor in 2016. He was with the Linnaeus Univ ersity\, Sweden between September 2009 and December 2010 as a visiting res earch for a collaboration\, which is still going on\, on electromagnetic m odeling of submarine power cables and flow acoustics. His research interes ts include mathematical modeling in general and rigorous methods applied t o electromagnetic and acoustic scattering problems\, such as Wiener-Hopf a nd mode-matching techniques.\n\nSpeaker(s): Prof. Gokhan Cinar\, \n\nAnkar a\, Ankara\, Türkiye LOCATION:Ankara\, Ankara\, Türkiye ORGANIZER:ozergul@metu.edu.tr SEQUENCE:0 SUMMARY:[Legacy Report] IEEE AP/MTT/EMC/ED Turkey Chapter Seminar Series -- Seminar 3 URL;VALUE=URI:https://events.vtools.ieee.org/m/147503 X-ALT-DESC:Description: <br /><p>Speaker: Prof. G&ouml\;khan &Ccedil\;ınar \, Eskişehir Osmangazi University</p>\n<p>Topic: "Wiener-Hopf Analysis of Baltic HVDC Submarine Power Cable Measurement"</p>\n<p>Location: Middle E ast Technical University\, Ankara\, Turkey</p>\n<p>Abstract:&nbsp\;<span c lass="s1">In this talk\, the Wiener-Hopf analysis of TEM wave reflection a long a coaxial waveguide with a step discontinuity on the outer wall will be presented.
