A Novel Pinned Cover Design With an Array of Three-Dimensional n-Pole Elements for Low-Frequency Filtering of Microwave Circuit Packages

Nişancı, Muhammet Hilmi (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2018)

In the proposed study, a novel miniaturized cover design including three-dimensional (3-D) n-pole (two-, three-, and four-pole) elements, instead of a conventional pinned cover consisting of an array of pins with circular ...
Design of Homogeneous and Composite Materials From Shielding Effectiveness Specifications

Francesco De Paulis; Nişancı, Muhammet Hilmi; Antonio Orlandi; Marina Y. Koledintseva; James L. Drewniak (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2014)

A procedure to synthesize a suitable biphasic composite material from the given Shielding effectiveness (SE) specifications is proposed herein. In particular, this paper presents an analytic approach for calculating ...
EBG-Based Common-Mode Microstrip and Stripline Filters: Experimental Investigation of Performances and Crosstalk

Nişancı, Muhammet Hilmi (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2015)

The aim of this study is to analyze from a modeling and experimental point of view the filter effectiveness and the crosstalk among signal traces crossing the same common-mode filter based on electromagnetic bandgap ...
Efficient Analytical Prediction of the EMI Bandgap Limits of PEC-PMC Metallic Enclosures Hosting RF and Digital Circuits

Nişancı, Muhammet Hilmi; Francesco De Paulis; Antonio Orlandi (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2017)

A metal enclosure whose lid is covered by an array of metal pins is studied in this paper. The pins are able to realize a fictitious perfect magnetic conductor surface at the pin end, thus inhibiting cavity resonances and ...
Electromagnetic characterization of ceramic material produced with natural zeolite

Kanberoğlu, Baha; Nişancı, Muhammet Hilmi; Demirkıran, Ayşe Şükran (ELSEVIER SCI LTD, 2015)

The aim of this study is to investigate the electromagnetic characterization of ceramic panel produced with natural zeolite via considering the frequency-dependent transmission (T), reflection (R) and absorption (A) ...

Kanberoğlu, Baha; Nişancı, Muhammet Hilmi; Demirkıran, Ayşe Şükran (ELSEVIER SCI LTD, 2015)

The aim of this study is to investigate the electromagnetic characterization of ceramic panel produced with natural zeolite via considering the frequency-dependent transmission (T), reflection (R) and absorption (A) ...
EMC Europe

Nişancı, Muhammet Hilmi; Francesco De Paulis; Antonio Orlandi (IEEE, 2016)

This paper proposes closed form equations showing the relationships between the geometrical parameters of a grooved cover of a metallic enclosure and the associated stop band (or band-gap) in the frequency spectra of the ...
From Maxwell Garnett to Debye Model for Electromagnetic Simulation of Composite Dielectrics Part I: Random Spherical Inclusions

Francesco De Paulis; Nişancı, Muhammet Hilmi; Marina Y. Koledintseva; James L. Drewniak; Antonio Orlandi (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2011)

A semianalytical approach to obtain an equivalent Debye frequency dependence of effective permittivity for biphasic materials with random spherical inclusions from the well-known Maxwell Garnett (MG) mixing rule is proposed. ...
From Maxwell Garnett to Debye Model for Electromagnetic Simulation of Composite Dielectrics-Part II: Random Cylindrical Inclusions

Nişancı, Muhammet Hilmi; Francesco De Paulis; Marina Y. Koledintseva; James L. Drewniak; Antonio Orlandi (IEEE, 2012)

A mixing rule in the theory of composites is intended to describe an inhomogeneous composite medium containing inclusions of one or several types in a host matrix as an equivalent homogeneous medium. The Maxwell Garnett ...
IEEE International Symposium on Electromagnetic Compatibility

Nişancı, Muhammet Hilmi; Francesco De Paulis; Antonio Orlandi (IEEE, 2017)

An effective technique for reducing electromagnetic interference within enclosures hosting microwave circuits is based on an artificial Perfect Magnetic Conductor (PMC) surface. This fictitious surface can be obtained by ...
