Guido Lombardi was born in Florence, Italy, on December 8, 1974. He received the laurea degree (summa cum laude) in telecommunications engineering from the University of Florence, Italy, in 1999 and the Ph.D. degree in electronics engineering from the Polytechnic of Turin, Italy, in 2004.
In 2000-2001, he was an Officer in the Italian Air Force. In 2004, he was an Associate Researcher with the Department of Electronics, Polytechnic of Turin, and in 2005 he joined the same department as an Assistant Professor.
In 2003, he was a Research Visitor with the Department of Electrical and Computer Engineering, University of Houston, Houston, TX, USA.
He was a member of the Organizing Committee of the International Conference on Electromagnetics in Advanced Applications (ICEAA), Turin, Italy (IEEE sponsored), for the 2001 and 2003 editions and as the ICEAA Scientific Secretariat and reviewer for the 2005 and 2007 edition.

His research areas comprise analytical and numerical methods for Electromagnetics, study of diffraction, Wiener-Hopf method, and design of microwave passive components.
A) Numerical methods for Electromagnetics: the research activity is focused on the solution of frequency domain formulations of electromagnetic problems using partial differential equations (PDE) and integral equations (IE). Theoretical and computational aspects of finite-element method for PDE and method of moments for IE are investigated. The computational precision in finite-element method and method of moment’s codes is deeply investigated together with the inclusion of electromagnetic singularity modeling: new vector basis fucntions are proposed. The numerical codes are written using C++, Fortran 90/95, and Matlab in an object oriented framework.
B) Study of diffraction: the research is focused on the interaction of electromagnetic waves with abrupt discontinuities: edges, wedges...
C) Wiener-Hopf method: the solution of generalized matrix Wiener-Hopf equations is studied using approximate techniques, i.e. Padé expansions and Fredholm integral equations. The method is applied to canonical structures as wedges and multiple half-planes.
D) Design of microwave passive components: waveguide problems with sharp discontinuities and the design of orthomode transducers have been investigated.

In the framework of the research activity Dr. Lombardi collaborates with the following scientific institutions: 1) Department of Electrical and Computer Engineering, University of Houston, Houston, TX, USA; 2) University of Tel Aviv, Tel Aviv, Israel; 3) Russian Academy of Science, St. Petersburg, Russia; 4) University of St. Petersburg, St. Petersburg, Russia; 5) University of Illinois at Chicago, Chicago, IL, USA.
Dr. Lombardi received the Raj Mittra Travel Grant award, as Junior Researcher, at the 2003 IEEE AP-S International Symposium and USNC/CNC/URSI National Radio Science Meeting, Columbus, OH, USA.
In september 2003 Dr. Lombardi has applied for a patent regarding his research activity on the study of singular electromagnetic fields with numerical methods (Publication Number: WO/2005/024674, At present the patent application is exclusively licensed worldwide to Reverb Communications LLC, NV, USA: agreement date february 11, 2006.
Dr. Lombardi has been invited for a "Lecture" at IEEE Multigroup (APS-MTT-MAG) Section, Houston, TX, USA, Nov. 17, 2003 and at Sandia National Laboratories, Albuquerque, NM, USA, June 29, 2004. The lecture were about the research activity of Dr. Lombardi on singular vector basis fucntions for Finite Methods.
He is reviewer of the following scientific journals:
1) IEEE Antennas and Wireless Propagation Letters; 2) IET Microwaves, Antennas & Propagation; 3) Electronics Letters, IET; 4) International Journal for Numerical Methods in Engineering, Wiley.
