Wireless power transfer (WPT) is one of the most promising technologies opening the huge market currently in mobile devices and electric vehicles, and it expends the future applications to biomedical implants, wearable devices, IoT sensors, and so on. The WPT technology provides convenience and safety with its wireless connection, however, it is true that our electromagnetic environment is threatened by the unwanted electromagnetic field from the WPT system, and the concerns on the electromagnetic interference to other electronic devices or human bodies are consequently increasing.

This talk covers WPT technology and the issues related with the electromagnetic compatibility and electromagnetic field. Beginning with the basic concept and applications of the WPT system, recent advances in technical solutions for electromagnetic safety aspects of wireless power transfer system are reviewed. The current issues on standardization including the human body safety and the future technologies will be discussed, to eventually find out the directions to get answers for the questions on the electromagnetic safety of WPT systems.

Parabolic mirrors are useful in radiating impulse-like waveforms. The antenna subsystem consists of a paraboloidal-reflector illuminated by a pair of conical transmission lines. Because of the spherical TEM feed, this antenna is non-dispersive. For an applied fast-rising voltage function, the radiated electric field spectrum is flat over two decades of frequencies. Some fundamental differences between frequency independent antennas (ex:log-periodic dipoles) and the present non-dispersive time-domain antennas will be discussed. Familiar concepts such as antenna gain and radiation pattern need to be redefined for time-domain antennas. Design, fabrication, working principles and performance of this class of antennas are discussed. Such a radiating system has resulted in an emerging technology with many military and civilian applications, some of which will also be discussed.

About the talk: Antennas are wave mode changers, that are classically described by a set of antenna parameters such as input impedance, gain, directivity, antenna factor and radiation diagram. Due to progressing complexity and integration of transmission systems, the exact knowledge of these parameters is getting more and more important. For the measurement of quantities conforming to standards, different measurement setups in absorber chambers and on open-area test sites exist. With progressing computational capabilities, computationally intensive methods based on near-field-to-far-field transformation gain importance. Flying measurement platforms based on autarkic multi-copters are used for the characterization of large stationary antenna systems. The talk shows some new developments. About the speaker: Thomas Kleine-Ostmann was born in Lemgo, Germany, in 1975. He received the M.Sc. degree in Electrical Engineering from the Virginia Polytechnic Institute and State University, Blacksburg, VA, USA, in 1999, the Dipl.-Ing. degree in Radio Frequency Engineering from Technische Universität (TU) Braunschweig, Germany, in 2001, and the Dr.-Ing. degree from TU Braunschweig, Germany, in 2005. Since 2006, he has been with the Electromagnetic Fields Group, PTB, Braunschweig, working as a permanent scientist.Currently, he is working on realization and transfer of the electromagnetic field strength, electromagnetic compatibility, antenna measuring techniques and THz metrology. In 2007, he became head of the Electromagnetic Fields Group, in 2012, of the Electromagnetic Fields and Antenna Measuring Techniques Group, and in 2020, of the Department High Frequency and Electromagnetic Fields. Dr. Kleine-Ostmann is a lecturer at TU Braunschweig since 2007. After his habilitation in the field of radio frequency engineering he was appointed Privatdozent becoming an external faculty member in 2014. He is giving lectures on Microwave and WirelessMetrology. Dr. Kleine-Ostmann is a member of the VDE and the URSI. He received the Kaiser-Friedrich Research Award in 2003 for his work on a continuous-wave THz imaging system.
