Tutorial 1: Machine learning enabled wearables for plants and humans at nano scale
Prof. Qammer H. Abbasi, University of Glasgow, UK
Tutorial length: 1 hour
Description: Advancement in nanotechnology has made it possible to manufacture sensors, circuits and devices measuring only nano-meters in size. This development is creating an extraordinary opportunity to observe, interact, and optimize physical systems from the very bottom. Wireless communication and networking at nanoscale, however, faces new challenges not encountered in conventional sensor networks. For example, nanoscale antenna calls for wireless communication in the Terahertz band, which encounters new path loss d noise phenomena posing significant challenges for many target applications of such networking. Nanoscale computing and communication is a new and rapidly growing field of research promoting collaboration between wireless networking, nanotechnology, and other fundamental disciplines. However, the research is in its early stages to realize communication and networking at the nanoscale. Currently, there is no definitive standard that provides guidelines and regulation for nanoscale communication and networking. This motivates this proposal to shed light on and promote this area of research and foster.
Objective: The objective of this tutorial is to present the opportunities, challenges, and recent advancements of this new and growing inter-disciplinary field explicitly in healthcare and agricultural technology domains using terahertz frequencies.

Tutorial 2: Guidance and Radiation of Metasurface-Waves
Prof. Stefano Maci, University of Siena, Italy
Tutorial length: 1 hour
Description: Metasurfaces constitute a class of thin metamaterials, which can be used from microwave to optical frequencies to create new electromagnetic engineering devices. At microwave frequencies, they are obtained by a dense periodic texture of small elements printed on a grounded slab. Changing the dimension of the elements, being the sub-wavelength 2D-periodicity equal, gives the visual effect of a pixelated image and the electromagnetic effect of a modulation of the equivalent local reactance. The modulated metasurface reactance (MMR) so obtained is able to transform surface or guided waves into different wavefield configurations with required properties. The MMR allows a local modification of the dispersion equation and, at constant operating frequency, of the local wavevector. Therefore, a metasurface modulation permits addressing the propagation path of a surface wave, according with a generalized Fermat principle, as happen in ray-field propagation in inhomogeneous solid medium. This may serve for designing lenses or point-source driven beam-forming networks. When the MMR exhibits a periodic modulation along the SW wavevector, the wave propagation is accompanied by leakage; i.e., a surface wave is transformed into a leaky-wave, and the structure itself becomes an extremely flat antenna. In every case, introducing asymmetry in the pixel allows for a polarization control. In this tutorial, the basic wave mechanisms will be reviewed showing several antenna applications.
