Raúl Rodríguez Berral received the Licenciado degree and the Ph.D. degree, both in Physics, from the Universidad de Sevilla in 2001 and 2008, respectively. He joined the Microwaves Group of the Universidad de Sevilla (MGUS) in 2002, when he was the recipient of a 4-year predoctoral scholarship awarded by the Spanish Ministry of Science and Technology. In 2006 he became "Profesor Ayudante" (Teaching Assistant) at the Department of Applied Physics 1, Universidad de Sevilla, where he became Profesor Contratado Doctor (Associate Professor, tenure track) in 2013 and Profesor Titular de Universidad (Associate Professor, tenure) in 2017.
During his Ph.D. program, he spent four months at the Department of Electrical and Computer Engineering, University of Houston, Houston, TX, under the supervision of Prof. David R. Jackson, and three months at the Dipartimento di Ingegneria Elettronica, "La Sapienza" University of Rome, Italy, working in Prof. Paolo Lampariello’s group. His early research work was focused on the modal analysis and excitation of waveguides and transmission lines using integral equation techniques. Specifically, he developed efficient techniques for the computation of the modal spectrum of planar layered waveguides, including complex modes (e.g. improper and leaky modes). He also developed semi-analytical techniques based on integral equation formulations for the computation of the modal spectrum and the current excited on both uniform and periodic planar transmission lines. These techniques allowed for a further, more fundamental study on the physical nature of the modes and the current excited in such structures. In the last decade his research efforts aimed at the circuit modeling of planar periodic structures such as microwave diffraction gratings and frequency selective surfaces. Within this line of research, he has contributed to the development of wide-band analytical equivalent circuits that model the scattering of electromagnetic waves by planar periodic structures. These analytical models not only constitute a very efficient computational tool but they also allow for the physical interpretation, in simple circuit terms, of “exotic” dynamic phenomena such as Rayleigh-Wood anomalies, extraordinary and anomalous transmission/reflection, induced transparency, etc.
In the framework of his research on equivalent circuit models, he was the advisor of a Ph.D. Thesis, some of whose results were awarded the "Young Engineer Prize" at the 2015 European Microwave Conference, for the work "Wideband equivalent circuit for non-aligned 1-D periodic metal strips coupled gratings". As a recognition for their work on high-frequency equivalent circuits, he and his collaborators Francisco Mesa and Francisco Medina were awarded the 2020 IEEE Microwave Magazine Best Paper Award for the paper entitled “Unlocking Complexity Using the ECA: the Equivalent Circuit Model as An Efficient and Physically Insightful Tool for Microwave Engineering” (IEEE Microwave Magazine, Vol. 19, No. 4, pp. 44-65, June 2018), which presented a review of their work on this line during the last decade. Other recognitions include the Best Paper Award at the “5th IEEE International Symposium on Microwave, Antenna, Propagation and EMC Technologies for Wireless Communications” (Chengdu, P.R. China, Oct. 29-31 2013), for the work entitled “Closed-form expressions for modeling diffraction at printed dipole-based FSS”, Best Paper Award finalist in the category “Antenna Theory” at the “8th European Conference on Antennas and Propagation, EuCAP 2014”, (The Hague, Netherlands, Apr. 6-11, 2014) for the work entitled 'Circuit model for patch/slot-based frequency selective surfaces under conical incidence' and three consecutive years secondary award (“accesit”) winner at the URSI Spanish national symposium (2012, 2013, 2014).
Raúl Rodríguez Berral has co-authored 39 journal papers (among them 20 IEEE Transactions, 5 IEEE Letters and 1 award winning IEEE Magazine) and over 100 contributions to international and national symposiums. His h-index is 20 (WoS, Scopus). During the last 10 years he has participated in 4 national and 1 regional research projects.
