Invitation

Dear all,

Please be invited for the 1^st April 2025 edition of the Center for Wireless Technology (CWTe) bi-monthly^* colloquium webinar.

CWTe will have two speakers in this colloquium/webinar on interesting wireless topics:

Vojkan Vidojkovic (TU/e) - Mm-wave circuits for communication and sensing
Wim Korevaar (TNO /TU/e) - Laser Satellite Communications: Design and In-Orbit Demonstration of the Fastest Laser Communication Terminal (* given its compact size of 10×10×10 cm and weight of only 1 kilogram)

Abstracts and Speakers

Mm-wave circuits for communication and sensing by Vojkan Vidojkovic (TU/e)

First Abstract: In the last decade wireless communications experienced exponential growth. Number of connected devices exceed the number of people on earth and the data rates keep increasing. The next wave in the wireless technology will be about sensing the environment. The applications are very versatile. They start with automotive industry with well known car radar and driver monitoring. Next, there are many applications in industry that are related to non-destructive material testing. High performance communication and sensing systems require wide bandwidths. Therefore, circuits operating at mm-wave frequencies are gaining attention from the industry and academia. The goal of this presentation is to approach mm-wave communications and sensing from application, system, circuit perspective, identify challenges and finally show examples how to address them from circuit perspective.

First speaker: Vojkan Vidojkovic (TU/e)

Biography: Vojkan Vidojkovic got MsC degree in 1999 from the University of Nis in Serbia. In 2007 he got PhD degree from the Eindhoven University of Technology in the Netherlands. In the period from 2000 to 2008 he was working in Mixed-signal Microelectronics group (MsM) at the Eindhoven University of Technology, Philips Research and Sitel Semiconductor in the Netherlands. From 2008 until 2013 he was with Imec in Belgium working as principal researcher. From august 2013 until January 2020 he was working as a member of technical staff/technical lead at Intel in Germany. From January 2020 he is working as associate professor in IC design group at Eindhoven University of Technology. Vojkan Vidojkovic has 25 years of experience in the field of RF integrated circuits/systems/architectures for wireless communications (2G, 3G, 4G, 5G, mm-wave). As recognition for the scientific contributions to the solid state circuit community he served as TPC member of International Solid-State Circuit Conference (ISSCC) in 2015 and 2016. From 2020 Vojkan is a TPC member of European Solid-State Circuit Conference (ESSCIRC).

Laser Satellite Communications: Design and In-Orbit Demonstration of the Fastest Laser Communication Terminal * by Wim Korevaar (TNO / TU/e)

(* given its compact size of 10×10×10 cm and weight of only 1 kilogram)

Second Abstract: In recent years, free-space optical (FSO) satellite communication has gained increasing attention due to its unique advantages, including the vast available bandwidth in the terahertz (THz) regime of the electromagnetic (EM) spectrum, license-free operation, enhanced security, and low power consumption.

In the Netherlands, we have designed, developed, and successfully demonstrated the fastest laser communication terminal, achieving a data rate of 1 Gbps—remarkable for its compact size of only 10×10×10 cm and weight of just 1 kilogram. In this presentation, we delve into the design aspects, operational performance, and in-orbit demonstration results. Additionally, we provide a broader perspective on the present and future of laser satellite communications.

Second speaker: Dr. ir. Wim Korevaar (TNO /TU/e)

Biography: Dr. ir. Wim Korevaar is a part-time university researcher at the Signal Processing Systems (SPS) Group, part of CWTe in the Department of Electrical Engineering at TU/e. In addition, he serves as a tech lead in the optical satellite communications program at the Dutch applied research institute. His main research interests include digital signal processing (DSP), modem design, end-to-end system analysis, and multiple-input multiple-output (MIMO) techniques. Wim is passionate about collaborating with (PhD) students and colleagues on pioneering ideas for the next generation of optical satellite communication systems. He actively fosters collaborations between academia, applied research institutes, space agencies and industry to drive innovation in the field.
