Marcos D. Fernandez received his degree in telecommunications engineering from the Universitat Politècnica de Catalunya (UPC), Spain in 1996, and his Ph.D. from the Universidad Politécnica de Madrid (UPM) in 2006. He joined the Universidad de Castilla-La Mancha in 2000, where he is now an associate professor in the Department of Electrical, Electronic, Automation and Communications Engineering. Since 2021,

he has been Dean of the Escuela Politécnica de Cuenca. He has authored or co-authored several papers in peer-reviewed international journals and conference proceedings. His research interests are empty substrate-integrated waveguide (ESIW) devices, and their manufacture and applications.

José A. Ballesteros received his degree in telecommunications engineering from the Universidad de Alcalá de Henares (UAH), Spain in 2009, and his Ph.D. from the Universidad Politécnica de Madrid (UPM) in 2014. He joined the Universidad de Castilla-La Mancha in 2007, where he is now an associate professor in the Department of Electrical, Electronic, Automation and Communications Engineering. He has authored or co-authored

several papers in peer-reviewed international journals and conference proceedings. His research interests are empty substrate-integrated waveguide (ESIW) devices, and their manufacture and applications.

Ángel Belenguer received his degree in telecommunications engineering from Universidad Politècnica de València (UPV), Spain in 2000, and his Ph.D., also from UPV, in 2009. He joined Universidad de Castilla-La Mancha in 2000, where he is now a professor in the Department of Electrical, Electronic, Automation and Communications Engineering. He has authored or co-authored more than 50 papers in peer-reviewed internation-

al journals and conference proceedings and frequently acts as a reviewer for several international technical publications. His research interests include methods in the frequency domain for the full-wave analysis of open-space and guided multiple scattering problems, the application of accelerated solvers or solving strategies to new problems or structures, EM metamaterials, and empty substrate-integrated waveguide (ESIW) devices and applications.

Héctor Esteban received his degree in telecommunications engineering and his Ph.D. from the Universidad Politècnica de València (UPV), Spain, in 1996 and 2002, respectively. He worked with the Joint Research Centre of the European Commission in Ispra, Italy and with the European Topic Centre on Soil (European Environment Agency). In 1998 he rejoined the UPV, where he is a professor and Dean of the School of Tele-

communications Engineering. His research interests include methods for the fullwave analysis of open-space and guided multiple scattering problems, and CAD design of microwave devices, especially using new empty substrate-integrated waveguide technologies, and its characterization for use in space conditions.
