16:30 Keynote talk: Microwave Imaging for Medical Diagnostics
Panagiotis Kosmas
King's College London, (United Kingdom)
The talk will briefly introduce the principles of medical microwave imaging (MWI) and then review recent progress from Dr Kosmas' team on the development and validation of this technique for brain imaging. This will include a study on the impact of using a metasurface to enhance signal penetration as well as a comparison of two-dimensional and three-dimensional tomographic approaches.

17:00 Invited talk: Electromagnetic and Geophysical models to estimate wind speed from Sentinel 1 radar images - C band
Ali Khenchaf
ENSTA Bretagne (France)
SAR (Synthetic Aperture Radar) systems are commonly used to observe the globe, and in particular the sea surface, since they can offer high spatial resolution data. To exploit SAR data, a description of the relationship between electromagnetic backscatter and the sea surface is essential. Thus, it is possible to use empirical (geophysical) or EM models. In this paper, we investigated and presented models for sea surface radar backscatter calculations and then used to estimate wind speed from Sentinel-1 images.

17:20 Invited talk: A New Measurement Configuration for the Microwave Breast Cancer Imaging
Ibrahim Akduman, Aleksandar Janjic
Istanbul Technical University (Turkey)
In this paper it will be presented a new microwave measurement configuration for the breast cancer imaging. The system consists of 36 modified Vivaldi antennas located circularly in an alumina matching medium. The operating frequency of the system is 0.4-8Ghz. The imaging system is clinically tested with 322 patients and now in the process of medical certification. During the talk the clinical results will be presented as well.

In this paper, we present a cylindrical microwave imaging system based on a multi-frequency bi-focusing (MFBF) imaging technique using Extended Gap Ridge Horn antenna (EGRH) probe for medical applications. The proposed probe antenna is designed to operate between 0.5 GHz to 1 GHz and filled with a high permittivity material to have an impedance match to the human body. This system has been successfully simulated using CST Microwave studio

A recent area of concern is how to insure the continued functioning of critical elements of societal infrastructure amid increasing forms of terrorist activities. One new threat is the use of an HPEM source to create intentional electromagnetic interference (IEMI). This threat involves deliberately illuminating a facility or sub-system with a sufficiently intense EM field, to cause an interruption in the normal operation of the facility's electrical equipment.

18:15 Invited talk: Giant Magnetoimpedance Microwires for Sensor Applications
Arkady Zhukov, Paula Corte-Leon, Lorena Gonzalez-Legarreta, Mihail Ipatov, Juan Maria Blanco, Valentina Zhukova
Universidad del Pais Vasco (Spain)
The influence of post-processing (annealing and stress-annealing) on the Giant magnetoimpedance (GMI) effect in thin magnetic microwires is reviewed. High GMI effect has been observed in Co-rich magnetic microwires with vanishing magnetostriction coefficient. Post-processing including annealing or stress-annealing at adequate conditions allows further improvement of GMI effect in Co-rich magnetic microwires.
