About the Author
Eloy de Lera Acedo ([email protected]) was born in Spain in 1982. He received
the M.Sc. degree in electrical engineering (best graduate of the year distinction)
from University Carlos III of Madrid in 2005. Then he started working toward the
Ph.D. degree in telecommunications at the same university. From 2006 to 2007 he
worked at the Yebes Astronomical Center and stayed at the Netherlands Institute
for Radio Astronomy (ASTRON) working in the design of array antennas for radio
astronomy. Since 2007 he has a position in the Cavendish Laboratory, University of
Cambridge. His main research interests include ultra-wideband array antennas as
well as radio astronomy receivers.
