Stefano MADDIO

Curriculum

Stefano Maddio si è laureato con lode in Ingegneria Elettronica e ha conseguito un dottorato di ricerca in Elettronica e Telecomunicazioni presso l'Università di Firenze nel 2005 e 2009, rispettivamente. Dal 2010 al 2017 è stato assegnista di ricerca presso il Dipartimento di Ingegneria Elettrica e Telecomunicazioni, poi rinominato Dipartimento di Ingegneria dell'Informazione, presso la stessa università.

Da settembre 2017 a febbraio 2024 ha ricoperto il ruolo di Ricercatore a Tempo Determinato (Tipo A e poi Tipo B). Da marzo 2024 è Professore Associato presso l'Università di Firenze.

Presso l'Università di Firenze ha collaborato alla didattica di numerosi corsi, tra cui:

"Sistemi Wireless" (oggi "Tecnologie e Sistemi per Applicazioni Wireless") ed "Elettronica a Radiofrequenza" (oggi "Elettronica dei Sistemi a Radiofrequenza") dal 2010,
"Teoria e Tecnica delle Onde Elettromagnetiche" e "Sistemi di Antenne" dal 2015.

Ha tenuto come unico titolare i corsi di:

"Bioelettromagnetismo" e "Bioelettromagnetismo Applicato" dal 2017 a oggi,
"Sistemi di Antenne" dal 2024 a oggi.
Dal 2021 ha tenuto il corso di "Compatibilità Elettromagnetica" con il Prof. Stefani Selleri
Dal 2024 ha tenuto il corso "Bioelettricità e Bioelettromagnetismo" con il Prof. Federico Carpi.

È membro del Dottorato di Ricerca in Ingegneria dell'Informazione presso l'Università di Firenze dal ciclo XXXV fino a oggi e ha tenuto il corso di "Indoor Positioning". Attualmente è referente del curriculum "Elettronica, Elettromagnetismo e Sistemi Elettrici" dello stesso dottorato ed è inoltre membro del gruppo di riesame AVA3.

Interessi di ricerca:
La sua ricerca si concentra sulle tecniche e tecnologie per l'elettromagnetismo applicato, dalla progettazione alla realizzazione fino alla caratterizzazione e all'impiego sistemistico in dispositivi elettronici operanti ad alte frequenze. Il suo principale ambito di specializzazione è la tecnologia delle antenne intelligenti per applicazioni wireless, con particolare attenzione ai problemi di localizzazione wireless e ai sistemi di antenne per comunicazioni dedicate a corto raggio.

Contributi scientifici:
È autore o co-autore di oltre 50 articoli pubblicati su riviste internazionali di alto impatto con peer review e ha pubblicato più di 100 lavori tra conferenze internazionali, conferenze nazionali e riviste nazionali.

Inoltre, è:

Autore e co-autore di un libro,
Contributore a due capitoli di libri collettivi,
Guest editor di un numero speciale di una rivista internazionale.

I suoi attuali interessi di ricerca comprendono l'analisi e la progettazione di sistemi radiativi per la microelettronica, la tecnologia delle antenne intelligenti per applicazioni wireless, con particolare attenzione ai problemi di localizzazione wireless e ai sistemi di antenne speciali per comunicazioni dedicate a corto raggio, nonché la modellazione di microonde, dispositivi e circuiti.

È membro IEEE dal 2010 ed è anche membro della Società Italiana di Elettromagnetismo.

Curriculum

Sure! Here is the translated text without bold formatting:

Stefano Maddio graduated with honors in Electronic Engineering and obtained a Ph.D. in Electronics and Telecommunications from the University of Florence in 2005 and 2009, respectively. From 2010 to 2017, he was a research fellow at the Department of Electrical Engineering and Telecommunications, later renamed the Department of Information Engineering at the same university.

From September 2017 to February 2024, he served as Assistant Professor. Since March 2024, he has been an Associate Professor at the University of Florence.

At the University of Florence, he has contributed to the teaching of several courses, including:

"Wireless Systems" (now "Technologies and Systems for Wireless Applications") and "Radiofrequency Electronics" (now "Electronics of Radiofrequency Systems") since 2010,
"Theory and Technique of Electromagnetic Waves" and "Antenna Systems" since 2015.

He has been the sole instructor of the courses:

"Bioelectromagnetism" and "Applied Bioelectromagnetism" from 2017 to the present,
"Antenna Systems" from 2024 to the present.
Since 2021, he has co-taught the "Electromagnetic Compatibility" course with Prof. Stefani Selleri, and since 2024, the "Bioelectricity and Bioelectromagnetism" course with Prof. Federico Carpi.

He has been a member of the Ph.D. Program in Information Engineering at the University of Florence from cycle XXXV to the present and has taught the "Indoor Positioning" course. Currently, he is the coordinator of the "Electronics, Electromagnetics, and Electrical Systems" curriculum within the Ph.D. program and is a member of the AVA3 review group for the same program.

Research Interests:
His research focuses on techniques and technologies for applied electromagnetics, ranging from design to implementation and characterization, as well as system-level applications in high-frequency electronic devices. His main area of expertise is smart antenna technology for wireless applications, with a particular focus on wireless localization issues and short-range communication antenna systems.

Scientific Contributions:
He has authored or co-authored over 50 papers in high-impact peer-reviewed international journals and has published over 100 works, including international conferences, national conferences, and national journals.

Additionally, he is:

Author and co-author of a book,
Contributor to two collective book chapters,
Guest editor of a special issue of an international journal.

His current research interests include the analysis and design of radiating systems for microelectronics, smart antenna technology for wireless applications, with a focus on wireless localization and specialized short-range communication antenna systems, as well as the modeling of microwave devices and circuits.

He has been a member of IEEE since 2010 and is also a member of the Italian Electromagnetics Society (SIEM, Società Italiana ElettroMagnetismo).
