Journal Article
Waltner, D., Gnutzmann, S., Tanner, G., & Richter, K. (2013). Subdeterminant approach for pseudo-orbit expansions of spectral determinants in quantum maps and quantum graphs. Physical Review E, 87(5), Article 052919. https://doi.org/10.1103/PhysRevE.87.052919

We study implications of unitarity for pseudo-orbit expansions of the spectral determinants of quantum maps and quantum graphs. In particular, we advocate to group pseudo-orbits into sub-determinants. We show explicitly that the cancellation of long...

Presentation / Conference Contribution
Baharuddin, M. H., Smartt, C., Maricar, M. I., Thomas, D. W., Gradoni, G., Creagh, S. C., & Tanner, G. (2018, August). Analysis of Nonstationary Emissions for Efficient Characterization of Stochastic em Fields. Presented at International Symposium and Exhibition on Electromagnetic Compatibility (EMC EUROPE 2018), Amsterdam, Netherlands

A statistical approach using field-field correlation functions which is obtained from two-probe time domain measurement is used to characterize the radiation from complex devices. The time-frequency analysis provided by the measurement data has shown... Read More about Analysis of Nonstationary Emissions for Efficient Characterization of Stochastic em Fields.

Transfer operator approach for cavities with apertures
Presentation / Conference Contribution
Gradoni, G., Creagh, S. C., & Tanner, G. (2016, August). Transfer operator approach for cavities with apertures. Presented at 2016 URSI International Symposium on Electromagnetic Theory (EMTS), Espoo, Finland

We describe a representation of the boundary integral equations for wave propagation in enclosures which leads to a direct description of transport and dynamical characteristics of the problem. The formalism is extended to account for arbitrary and p... Read More about Transfer operator approach for cavities with apertures.

Time domain measurement of near field emissions from complex PCBs
Presentation / Conference Contribution
Thomas, D., Greedy, S., Smartt, C., Nasser, H., Baharuddin, M., Gradoni, G., Creagh, S., & Tanner, G. (2016, October). Time domain measurement of near field emissions from complex PCBs. Presented at 46th European Microwave Conference, London, UK

This paper discusses how the measurements of the near-field emissions in the time domain can be used to characterize the broadband emissions from complex sources such as multifunctional Printed Circuit Boards (PCBs). The near- fields, transverse to t... Read More about Time domain measurement of near field emissions from complex PCBs.

A fast and efficient approach for simulating ultrasonic waves and their interaction with defects in periodic structures
Presentation / Conference Contribution
Malik, M. K., Chronopoulos, D., Tanner, G., Essa, Y., & De La Escalera, F. (2018, September). A fast and efficient approach for simulating ultrasonic waves and their interaction with defects in periodic structures. Paper presented at International Conference on Noise and Vibration Engineering (ISMA2018), Leuven, Belgium

An approach for simulating transient wave propagation in periodic waveguides is presented. Free and forced propagation of ultrasonic waves is modelled in one dimensional periodic structures. The interaction of ultra-sonic waves with structural inhomo...
