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 ...

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. ...
