Imaging and target tracking millimeter-wave radar for space applications

Landing and docking in space require imaging and target tracking sensors that can operate independently of the lighting situation and at the same time have good resolution and precise spatial localization with minimum data rates. Millimeter-wave radar sensors and real-time image processing can meet these requirements.

Energy Harvesting

Investigation into Power Generation in Self-Powered Sensor Networks

For energy harvesting systems (EHS) are structures that collect energy from the environment and convert it into electricity. This technology represents an important alternative to battery operation in different applications. Current applications use linear EHS resulting in an inherent limitation of the power generated with it. In contrast, nonlinear EHS, which can be represented as a modulated bistable oscillators with noise excitation, allow to overcome this limitation, while increasing the efficiency.

Multi-frequency multi-mode Terahertz screening for border checks

TeraSCREEN proposes to develop an innovative concept of multi-frequency multi-mode Terahertz (THz) detection with new automatic detection and classification functionalities. The system developed will demonstrate, at a live control point in Madrid-Barajas International Airport, the safe automatic detection and classification of objects concealed under clothing, whilst respecting privacy and increasing current throughput rates.

Sensors towards Terahertz

Sensors are an indispensable part of everyday’s life : In every small technical device many sensors are installed such as location and touch sensors in mobile phones, gas sensors in automobiles and incinerators that detect pollutants or step and pulse sensors in watches. However, many applications, especially in the fields of environmental sensors and bioanalytics, as well as in Real time Monitoring, require innovative Sensor concepts.

Biomedical Applications

Microwave Breastcancer Detection

Active approaches for microwave mammography are based on the dielectric contrast between healthy and malignant tissue. This allows a three-dimensional localization of one or possibly several tumors. Current research activities consider the heterogeneity of breast tissue which is a major challenge for reliable three-dimensional tumor detection.

Radar-based SHM

Radar-based Structural Health Monitoring

In-service detection of material failures based on an integrated sensor network is the main goal of structural health monitoring (SHM). We are developing new and integrated methods (hardware and software) for radar-based SHM applications based on microwave and millimeter wave radiation.

Internet use and technology has penetrated deeply and fast in society everyday life as no other technology before in the last decades and is expected to do in the future. The enormous flux of data transferred via wireless networks, increasing at exponential pace, makes today’s state of the art networks soon outdated. Large parts of the society are deprived of adequate access to Internet due to the high costs, long deployment time of optical fibres and inadequate performance of wireless networks. This inequality will most likely pertain in the next years.

Millimetre and Terahertz waves are the most promising solution to support the increasing data throughput and to be a credible fibre complement for the last miles. The TWEETHER aim is to realise the millimetre wave Point to multi Point segment to finally link fibre and distribution for a full three segment hybrid network, that is the most cost-effective architecture to reach mobile or fixed final individual client.

The TWEETHER project intends to foster smart wireless network architecture for high capacity everywhere outdoor data distribution, in gigabit class, that other technologies cannot support, at low operating cost. High spectrum and energy efficient W-band (92-95GHz) technology will be developed. A powerful and compact transmission hub based on a novel traveling wave tube power amplifier with performance precluded to any other technology and an advanced chipset in a compact terminal will be realised. The TWEETHER system will be tested in a real operating environment. Integrated smart networks of backhaul for 4G and 5G small cells and of access for residential houses are the targeted market that benefits from the actual light regulation of W-band. A big company Thales Electron Devices, four SMEs, Bluwan, OMMIC, HFSE, Fibernova, and three top Universities, Lancaster, Goethe Frankfurt, Politecnica de Valencia, join their expertise to successfully tackle the formidable challenges of the TWEETHER project.

The Goethe Leibniz Terahertz Center will perform travelling-wave tube and amplifier development, as well as testing. It will also test MMIC chipset for the terminal and base station of the TWEETHER system and will participate in the system design. This work is based on the expertise of the group on TWTA design from pervious projects, such as OPTHER (Link) and PhD thesis (Link)
