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 ...
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 ...
Experimental Validation of a 3D FSS Designed by Periodic Conductive Fibers Part-1: Band-Pass Filter Characteristic

Teşneli, Ahmet Yahya; Teşneli, Nigar Berna; Üstüner, Fatih; Ekrem Demirel; Francesco De Paulis; Antonio Orlandi (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2017)

This study covers the design, manufacturing, and experimental electrical tests for a novel three-dimensional (3-D) band-pass frequency selective surfaces (FSS) containing continuous and discontinuous conductive fibers. The ...
Experimental Validation of a 3D FSS Designed by Periodic Conductive Fibers Part-2: Band-Stop Filter Characteristic

Teşneli, Nigar Berna; Teşneli, Ahmet Yahya; Üstüner, Fatih; Ekrem Demirel; Francesco De Paulis; Antonio Orlandi (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2017)

In this study, an X-band band-stop frequency selective surface (FSS) consisting of aligned finite length periodic conductive cylindrical fibers embedded in a dielectric host material is designed, manufactured, and electrically ...
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 ...
Removable EBG-Based Common-Mode Filter for High-Speed Signaling: Experimental Validation of Prototype Design

Michael A. Varner; Francesco De Paulis; Antonio Orlandi; Sam Connor; Michael Cracraft; Bruce Archambeault; Nişancı, Muhammet Hilmi; Danilo Di Febo (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2015)

A new common-mode filter structure based on planar electromagnetic bandgap (EBG) technologies is designed, fabricated, and measured. It is based on a previously proposed geometry, implementing a sequence of two or more ...
