Wireless energy harvesting (WEH) and wireless power transfer (WPT) are two closely related topics: they both employ a critical device – a rectenna, which is defined as the combination of an antenna and a rectifier. It receives RF/microwave waves and converts them into DC energy/power which can then be stored or used by application devices. It is expected this technology would produce higher energy conversion efficiency than photovoltaic technology for electromagnetic waves in the future. Energy conversion efficiency is the critical and most important element for wireless energy harvesting (WEH) and wireless power transfer (WPT). How to design an efficient rectenna is a key challenge since this is a non-linear device whose performance is heavily affected by the input power and the load impedance. WEH is motivated by the demand for a low-cost and low-power supplier for many Internet-of-Things (IoT) devices. The conventional battery is good for many applications, but it has to be changed now and then which means a waste of human resources and materials. Due to the widespread use of wireless systems, a lot of electromagnetic energies are around us and available in the ambiance environment at different frequencies (such as FM, TV, mobile, and Wi-Fi signals). Rectennas, especially broadband rectennas, are the ideal device to harvest these energies. WPT is another major breakthrough that has made wireless charging possible and will enable many more anticipated ubiquitous IoT, EV, and medical applications. Unlike WEH, WPT is normally narrow-band and could be near-field or far-field. Thus the design requirements are different from WEH although they both use rectennas. In this Lecture, we are going to 1) introduce the rectenna and review major historical events and developments; 2) provide a comprehensive review of rectenna designs (including different topologies and their comparison); 3) discuss the state-of-the-art designs (including such as the application of metamaterials and surfaces) and challenges (e.g. how to make it compact and efficient); 4) explain its applications in a range of WEH and WPT, including some very ambitious projects in the world. Furthermore, it will include some life and video demonstrations produced by our research group.

Antennas are normally made of metal in order to achieve high radiation efficiency. Unlike metal antennas, liquid antennas are a new type of antenna that has some unique features and gained a lot of attention recently. The University of Liverpool has been working in this area for many years. In this talk, the advantages, disadvantages, and challenges of using such a liquid antenna for real work applications will be discussed at the beginning, and then it will be followed by the latest development on the liquid material and the liquid antenna designs and development. A new concept of using gravity in making liquid antennas for beam-steering and GPS applications will be used as an example in this talk. Other antennas, such as a hybrid antenna of the dielectric resonant antenna (DRA) and magneto-electronic (ME) dipole will also be introduced and discussed. The talk will be finished with the introduction of a new design that is suitable for antenna diversity and MIMO applications. Some relevant activities at the High-Frequency Engineering Group at the University of Liverpool will also be introduced briefly.

Multi-wavelength lasers have emerged as a promising solution for a range of applications: from sensing to high-frequency signal generation or all-optical processing. For instance, they are an appealing solution to generate mm-wave or THz signals: besides the reduce footprint or the lack of required alignment, the coupling between modes leads to lower noise level. However, lasing is still a “winner takes it all” process, thus simultaneous emission at multiple wavelengths can be a challenging target to reach. A rather careful design or a precise control mechanism are typically required. In this talk, I will briefly review demonstrated schemes to implement multi-wavelength lasers on Photonic ICs, with a particular focus on laser designs compatible with (active) generic foundry platforms. I will discuss the difficult trade-off between flexibility, tunability and stability, and highlight the approach we chose relying on a phase-controlled optical feedback loop. Finally, I will present some of our recent results exploiting such multi-wavelength lasers for new applications such as spectral multiplication of frequency combs and wavelength conversion.

EM-based medical technologies are receiving increasing interest in the global scientific community. One of the most studied applications in this field is the use of microwaves for cancer diagnosis, particularly for breast cancer detection, made possible by the significant dielectric contrast between healthy and neoplastic tissues. Several microwave imaging prototypes for breast cancer detection have been proposed, some even tested in pre-clinical settings on volunteers and patients, demonstrating reasonable target detection capabilities in dense/medium-dense tissues. In this seminar, an overview of the work done and on-going at the University of Pavia investigating the potential of millimeter (mm-) waves for early-stage breast cancer detection in fat tissues will be disclosed. In particular, the main design steps will be shown and critically discussed. In addition, the perspectives of multi-modal approaches (based on mm-waves, Ultrasounds, and elastography) to improve the cancer detection capabilities in different breast compositions will be presented.
