Our research is to a high extent refl ected in the more than 80 PhD programs which are currently carried out. Our profi le magazine is therefore organized in brief presentations of each of our seven groups followed by short outlines of the individual PhD programs. Innovation is high on the agenda in recognition of society’s need for fresh ideas to sustain welfare and prosperity. Our PhD programs strongly support innovation, as many are carried out in fruitful collaboration with both Danish and international partners. Moreover, funding from competitive research grants is oft en obtained in collaboration with industry thereby securing an effi cient exchange of knowledge. In 2012 we generated 11 patent ideas – many leading to new products. Other innovative ideas resulted in prizes and awards as detailed in the section on “Awards and Public Outreach”. In 2012 our research was evaluated by an international expert panel. We are happy with the outcome showing that we have a competitive edge in many areas. In addition to our many ongoing projects, we have started a host of new research projects and initiatives. Some of these are large, long term eff orts allowing cutting edge research. To mention just a few: • Th e Danish Advanced Technology Foundation granted a platform project On demand diagnostic Ultrasound Imaging allowing continuation of the leading eff ort in ultrasound imaging • In collaboration with a consortium of companies we inaugurated PowerLabDK (Phase I). It represents one of the world’s most advanced facilities for research into future electric power systems • Our Centre for Applied Hearing Research has secured another four years of sponsorship from the Danish hearing aid industry and moreover – with support from the Oticon Foundation – our Hearing Systems group will establish the new Oticon Centre of Excellence for Hearing and Speech Sciences • Also supported by the Danish hearing aid industry we will set up a Center for Acoustic and Micro Mechanics. Th e center, which is the fi rst of its kind, is a joint eff ort with the DTU Department of Mechanical Engineering • We take part in the Human Brain project, which is one of the two EU Future and Emerging Technologies (FET) Flagship Projects that have obtained funding. We also participate in the Guardian Angels project which we hope will obtain similar funding in the future. As can be seen in “Facts and fi gures”, we have considerable activities going on in teaching and training. Our study programs continue to be fi lled to capacity. It should be noted that our many student projects at Bachelor and Master levels represent a considerable innovation eff ort to the benefi t of collaborative partners and to society. We hope you will enjoy reading about the innovative research we engage in, and we look forward to future contact and collaboration. Professor Kristian Stubkjær Head of Department 2 DTU ELECTRICAL ENGINEERING IN PROFILE 2013 Awards, honours and appointments Professor Ziolkowski for the Honorary Doctorate. Th e background for Professor Ziolkowski’s nomination is his research within electromagnetic metamaterials and the use hereof within antenna technology to establish the new fi eld of Metamaterial- Inspired Antennas. Th is facilitates highly miniaturized antennas which are essential for modern wireless communication. The Günther Laukien Prize Adjunct professor Jan Ardenkjær-Larsen was awarded the Günther Laukien Prize for his work in hyperpolarisation. Th e Günther Laukien Prize recognizes cutting-edge experimental Nuclear Magnetic Resonance (NMR) research with a high 2012 best DTU PhD Dissertation Award probability of enabling benefi cial new applications. Jan At the DTU PhD celebration party in October 2012 our then Ardenkjær-Larsen’s research focuses on hyperpolarized MR PhD student Ziwei Ouyang was awarded for the “Best DTU imaging where a technique has been developed which improves PhD Dissertation” of the year. the MR signal by 10,000 - 100,000 times and makes it possible Th e dissertation on “Advances in planar and integrated to determine whether tumours respond to the treatment off ered. magnetics” was judged to be of a very high quality presenting a number of ground breaking solutions. Ziwei Ouyang is also the author of an impressive number of publications as well as two Honorary Doctor applications for patents during his PhD study. European Acoustics Association Best Paper and Presentation Award 2012 PhD student Antoni Torras Rosell was honoured with the European Acoustics Association (EAA) Best Paper and Presentation Award 2012 at the International European conference on noise “Euronoise 2012”. Th e paper “A beam forming system based on the acousto-optic eff ect” describes a beam forming system that locates sound sources based on the acousto-optic eff ect, i.e. the interaction between sound and light. Professor Richard W. Ziolkowski, University of Arizona, DTU President Anders Bjarklev and Professor Olav Breinbjerg. Best paper award International Power Electronics In April 2012 professor Richard W. Ziolkowski from University and Motion Control Conference 2012 of Arizona, USA, was nominated Honorary Doctor by Industrial PostDoc Ziwei Ouyang and his DTU Elektro DTU President Anders Bjarklev. Professor Ziolkowski and colleagues received the IPEMC 2012 award for their paper DTU Elektro has a long common history in terms of a close “Decoupled power solution for dual-input isolated DC-DC collaboration with our Electromagnetic Systems group under the converters using four quadrants integrated transformers leadership of Professor Olav Breinbjerg who had recommended (FQIT)”. 3 DTU ELECTRICAL ENGINEERING IN PROFILE 2013 Th eir system makes the treatment easier, ensures better control, and furthermore has the advantage of a simpler installation of apparatus in the operation theatre. So far, the start-up company has spent two years improving the technology from its prototype stage till now. Venture Cup Idea Competition Th e Venture Cup Idea Competition fi rst prize in the Electro Prize 2012 “Cleantech & Environment” category was given to Kristian David B. Bæk, PhD from DTU Elektro, received the Electro Lindberg-Poulsen for his work in “Ultra-high effi ciency Prize 2012, awarded by the Danish Society of Engineers converters for fuel cell applications”. Th e idea is to increase the (IDA). David B. Bæk was nominated because of his signifi cant effi ciency of the so called power converters to be used in fuel contributions to the electro technical area at a very young cells
