I am delighted to announce we recently got one journal paper accepted in IEEE Transactions on Industrial Electronics. My PhD student Wen Junkai is one of the main contributors to this paper where I am the corresponding author, Congrats to him again. This paper focuses on a complex vector PI current controllers framework with the enhancement of disturbance rejection, stability, and dynamic response, which is suitable in high-power heavy-duty traction and propulsion systems. I am thinking about how to convert low TRL research output effectively to practical products with UK partners in the future to decarbonize the world. https://lnkd.in/gt99Nz8A

We are thrilled to share that our latest research paper, titled "New Rectification Technique Employing Auxiliary Rectifier for Resonance Control Achieving Compact Size and High Efficiency in CMOS," has been published in IEEE Solid-State Circuits Letters. In this paper, we present the design and realization of a compact, high-efficiency CMOS rectifier with a resonance control technique that employs the concept of a parallel rectifier. Our methodology involves the integration of two rectifiers: a main rectifier specifically designated for rectification purposes, and an auxiliary rectifier that serves for impedance matching as well as resonance control. The proposed CMOS rectifier with resonance control via a parallel rectifier presents a promising approach to achieving high efficiency and compact size, which can be highly beneficial for modern applications in wireless power and energy harvesting. I would like to extend my heartfelt gratitude to my Professor Ramesh K. Pokharel, Advisory Professor Naoki Shinohara, Assistant Professor Adel Barakat, and co-author Dr. Samundra K. Thapa for their valuable guidance and support throughout this work. The link to access the full paper is attached here:

This paper present #JUMP, the first system enabling practical bistatic and asynchronous joint communication and sensing, while achieving accurate target tracking and micro-Doppler extraction in realistic conditions. Their system compensates for the timing offset by exploiting the channel correlation across subsequent packets. Further, it tracks multipath reflections and eliminates frequency offsets by observing the phase of a dynamically-selected static reference path. JUMP has been implemented on a 60 GHz experimental platform, performing extensive evaluations of human motion sensing, including non-line-of-sight scenarios. In their results, JUMP attains comparable tracking performance to a full-duplex monostatic system and similar micro-Doppler quality with respect to a phase-locked bistatic receiver. ---- Jacopo Pegoraro, Jesus O.

Our most recent article, "An Electromagnetic-Compliant Scattering Model for Reconfigurable Intelligent Surfaces," has been published in IEEE eXplore. The article introduces a physics-based communication model for reconfigurable intelligent surface (RIS)-assisted wireless systems. This work was presented at EuCAP 2024. Specifically, our approach leverages a 2D formulation of electromagnetic (EM) fields based on Green’s functions, ensuring both simplicity and accuracy. By adhering to the fundamental laws of electromagnetism, we address the generation, propagation, and scattering of EM fields. The proposed model explains and analyzes the various diffraction orders present in the fields scattered by the RIS and helps predict their behaviour. This work is a product of the research I conducted at Institut Langevin - Ondes et images and ESPCI Paris - PSL.

This paper explores #Long #Range (#LoRa) waveform theory to quantify its orthogonality. The authors present expressions for the LoRa waveform in continuous and discrete time domains. The cross-correlation functions are expressed analytically in a general form that accounts for various configuration parameters including bandwidth and spreading factors. They also consider different cases where the signals are shifted, such as a time delay or frequency shift. ---- Fatma Benkhelifa More details can be found at this link: https://lnkd.in/gfVQz762
