Ultrasonic guided waves have been used successfully in structural health monitoring (SHM) systems to detect damage in isotropic and composite materials with simple and complex geometry. A limitation of current research is given by a lack of freely available benchmark measurements to comparatively evaluate existing methods. This paper introduces the extendable online platform Open Guided...Read More

Elastic guided waves constitute a promising approach for structural health monitoring (SHM) applications involving composite structures. Guided-wave SHM systems are composed of a network of ultrasonic sensors, which are permanently attached to a structural component. Besides monitoring, the supplementary capability of the network nodes to exchange information across this mechanical wave-guide itself, represents an innovative...Read More
Carbon fiber reinforced plastics (CFRP) are widely used in lightweight marine structures due to their high strength and superior fatigue behaviour. In this paper, we will present an innovative methodology for simultaneous load and structural monitoring of a CFRP rudder stock as part of a big commercial vessel. Experimental results are presented here from a...Read More
This paper presents a novel approach for the detection of surface damage in metallic structures, where the electromagnetic waveguide forms a union with the structure to be inspected. The sensing concept in such jointed electromagnetic waveguides will be described here and measurement results will be presented using a hollow metallic waveguide on an aluminium sample....Read More
Hemispherical and cylindrical antenna arrays are widely used in radar-based and tomography-based microwave breast imaging systems. Based on the dielectric contrast between healthy and malignant tissue, a three-dimensional image could be formed to locate the tumor. However, conventional X-ray mammography as the golden standard in breast cancer screening produces two-dimensional breast images so that a...Read More
Abstract: Digital data communication, i.e. the transmission of discrete encoded information, is already pervasive, but possesses an ever-growing importance for everyday life in contemporary societies. The underlying physics can vary vastly, e.g., between fiber-optic communication and wireless mobile cellular networks. However, at least three unifying elements can clearly be identi ed, i.e. modulation, transmission and demodulation....Read More
Award for the winner in the competition for best scientific publication in high impact international journals in 2017 (given by the Director of the Institute of Fluid-Flow Machinery, Polish Academy of Sciences, Gdansk, Poland) Certificate is related to the paper: Luca De Marchi, Alessandro Marzani, Jochen Moll, Paweł Kudela, Maciej Radzienski, Wiesław Ostachowicz: A pulse...Read More
I participated in the SHM in Action session as part of the 9th European Workshop on Structural Health Monitoring in Manchester (UK). An SHM demonstrator was presented there that shows the data communication capabilities of guided ultrasound waves. This additional feature might be exploited in future guided wave-based SHM systems. More information on this experiment...Read More
