Publications and preprints
The page is organized into two sections, reflecting the ``dual nature'' of my research profile:
Notes. (i) As a rule of thumb, a PDF copy of any document on this page is always the most uptodate version of the document itself.
(ii) Some journals are now making their archives accessible for free. Yet, many links on this page lead to articles
behind a paywall. In all cases, I can provide a copy on request (just send me an email at the address
salvo.tringali (at) gmail.com).

PhD thesis of the Università di Reggio Cal., Italy
Speciality: electronics engineering  Subspeciality: computational electromagnetics
Laurea thesis of the Università di Reggio Cal., Italy
Speciality: electronics engineering  Subspeciality: computational electromagnetics
Title of the thesis: 
Diagonalization of nonselfadjoint operators resulting from the study of the scattering of electromagnetic fields by ideal cylindrical conductors (in Italian) 
Date of defense: 
25 January 2005 
Thesis directors: 
Giovanni Angiulli (Researcher, Università di Reggio Cal.)


Mario Versaci (Associate professor, Università di Reggio Cal.)

Note. In Italy, the laurea was the main academic degree until the reforms following the Bologna process. A laurea was, actually, a long university degree (5 years for engineers), which concluded with the presentation of a thesis (usually based on experimental work) in front of a jury.
