10:10-10:30:Neural Network-based Approaches for the Spatial Localization of Microwave Sources with Stochastic Radiation
Zoran Stanković, Nebojša Dončov, Biljana Stosić, University of Niš, Serbia

In the past two decades, smart techniques based on the artificial intelligence have found their place as a very efficient and powerful tool for modeling and optimization in the field of microwave engineering. Having in mind a growing general interest for the artificial intelligence, the aim of this workshop is to give an insight into the state-of-the art and future directions in the field of smart modeling techniques for different microwave applications. The majority of presentations will refer to the applications of artificial neural networks, as the most frequently used smart technique in the field of microwaves, for modeling and optimization of passive and active microwave devices, as well as other applications such as spatial localization of microwave sources. Moreover, the workshop will cover applications of other smart techniques, among them support vector machine methods, symbolic regression, and evolutionary algorithms.

15:20-15:30: Conclusion and Discussion

Usually, the electromagnetic and electronic parts of standard communication system, such as antennas, amplifiers, oscillators etc. are analyzed and designed separately. However, the recent progress of active electromagnetic structures and systems is changing this approach and merging the fields of electromagnetics and RF/microwave engineering. Here, the electronic and electromagnetic parts are joined into an entity with novel physical phenomena such as negative, switching, or time-varying capacitance/inductance. Applications associated with this novel approach include advanced wireless power transfer systems, broadband/ non-reciprocal/ self-oscillating antennas, metasurfaces, filters, hybrids and phase shifters, just to mention a few. This workshop gathers together a team of prominent experts that will give an overview of both the background theory and applications of this exciting research field.
