Analysis of structures formed with shunt capacitor seperated by transmission lines
Cakmak, Gokhan (Kadir Has Üniversitesi, 2018)Bobin ve kondansatorlerden olusan merdiven devreler hakkinda literaturde bircok calisma bulunmaktadir. Fakat genellikle agir ve buyuk olduklari icin uretilebilecek deger araliklarinin sinirli olmasi ve mikrodalga frekanslardaki ... -
BROADBAND DOUBLE-MATCHING VIA LOSSLESS UNSYMMETRICAL LATTICE NETWORKS
Sengul, Metin (Istanbul Univ, Fac Engineering, 2012)In this paper, a broadband double-matching network design algorithm has been presented. In the network, an unsymmetrical lattice network has been used. The branch impedances of the lattice network are composed of singly ... -
DESIGN TABLE FORMATION OF STEPPED IMPEDANCE PROTOTYPE FILTERS
Sengul, Metin (Istanbul Univ, Fac Engineering, 2010)In literature, there exist some tables containing normalized element values, to design low-pass lumped-element prototype filters with several different responses like maximally flat or equal-ripple. In this work, an algorithm ... -
High-pass and low-pass mixed element lossless two-port networks as phase shifters
ÇAKMAK, Gökhan (Kadir Has Üniversitesi, 2022-07)Phase shifters are one of the sub-units in many systems. In active-phased array radar (APAR) systems, digital phase shifters (switched line, reflection, loaded-line, and high pass/low-pass which is the smallest in volume ... -
ON THE INVERSE POINT-SOURCE PROBLEM OF THE POISSON EQUATION
Yilmaz, Melek; Sengul, Metin; Geckinli, Melih (Istanbul Univ, Fac Engineering, 2005)In this work, a basic inverse heat conduction problem of a simple 2-D model with steady state heat source is taken into view. The physical problem is for a square region with uniform thermophysical properties and a point ... -
SYNTHESIS OF LOSSLESS LADDER NETWORKSWITH SIMPLE LUMPED ELEMENTS CONNECTED VIACOMMENSURATE TRANSMISSION LINES
Sengul, Metin (Istanbul Univ, Fac Engineering, 2010)An algorithm has been proposed, to synthesize low-pass, high-pass, band-pass and band-stop lossless ladder networks with simple lumped elements connected via commensurate transmission lines (Unit elements, UEs). First, the ...
