Presentation title
Microwave Imaging

Abstract
The presentation is divided into two parts. The first one will give an overview
about imaging capabilities using microwaves instead of optical systems. The
second part is about indoor short-range localization systems.

A subsection of microwaves are millimeter waves covering the frequency range of
30 GHz to 300 GHz. This special frequency range has the advantage that various
materials appear transparent for electromagnetic waves. Moreover, the short
wavelength guarantees resolution in the millimeter region or even less.

After a short introduction into principles of wave propagation, the
presentation will focus on practical examples to discuss the capabilities but
also the limits of such imaging methods. Typical application fields are
security systems or non-destructive testing methods. In the last-mentioned
field, other non-imaging but contact-less sensing methods based on Terahertz
radar and high-precision magnetic field measurements are presented to introduce
current research activities at the Magdeburg-Stendal University.

In the second part, the results of a currently ongoing project at our
university will be presented. The ROSI 3D project is based from the technology
point of view on the RFID technology. The goal is the accurate radio
localization of objects in a dynamic environment. The presentation will explain
the two main project approaches, namely a 3D model for wave propagation based
on cellular systems as well as a dynamic model to simulate interferences of
different signals. Examples show the capabilities of the described approaches.

CV of Sebastian Hantscher

Sebastian Hantscher was born in 1980. From 1999 to 2004 he studied Information
System Technology with the main focus on microwave engineering at the Dresden
University of Technology, Germany. During this time, he was responsible for
exercise courses in mathematics for electrical engineers.  In 2005 he was with
the Microelectronics institute of the Johannes Kepler University in Linz,
Austria. Apart from teaching, he worked on different research projects with the
main focus on ultra-wideband radar. In 2008, he finished his PhD thesis about
radar imaging algorithms with distinction.  In 2009, he joined the Fraunhofer
Institute for High Frequency Physics and Radar Techniques in Wachtberg near the
former German capital of Bonn. As project leader he was responsible for an
international research project funded by the European Commission. The goal of
the project was the development of a prototype of an imaging body scanner for
airport security checks. Besides of the necessary administrative tasks, his
technical development focused on rotating multi-channel radar at 94 GHz using
the principle of the synthetic aperture. Moreover, he contributed to security
related projects funded by the Department of Homeland Security. After the
nomination to a team leader, he represented the institute in aspects of “Sensor
Systems for Security Applications”.  In 2012, he joined the Magdeburg-Stendal
University of Applied Sciences. Since 2016, he is professor for High Frequency
Technologies and Vice-Dean for research and technology transfer. Moreover, he
is Senior Member of the IEEE as well reviewer of scientific journals and
European research projects.
