Transfer operator approach to ray-tracing in circular domains (2020)
Journal Article
Slipantschuk, J., Richter, M., Chappell, D. J., Tanner, G., Just, W., & Bandtlow, O. F. (2020). Transfer operator approach to ray-tracing in circular domains. Nonlinearity, 33(11), 5773-5790. https://doi.org/10.1088/1361-6544/ab9dca

The computation of wave-energy distributions in the mid-to-high frequency regime can be reduced to ray-tracing calculations. Solving the ray-tracing problem in terms of an operator equation for the energy density leads to an inhomogeneous equation wh...

Wave scattering in coupled composite plates (2019)
Presentation / Conference Contribution
Aimakov, N., Tanner, G., & Chronopoulos, D. (2019, June). Wave scattering in coupled composite plates. Presented at Inter.noise 2019, 48th International Congress and Exhibition on Noise Control Engineering, Madrid, Spain

Establishing the wave propagation characteristics at plate junctions is of great importance in the prediction of vibrational energy transmission across complex structures. A hybrid approach combining the finite element (FE) and the wave finite elemen... Read More about Wave scattering in coupled composite plates.

Philosophical Transactions A: Mathematical, Physical and Engineering Sciences, 376, Article 20170455. https://doi.org/10.1098/rsta.2017.0455

This paper reviews recent progress in the measurement and modelling of stochastic electromagnetic fields, focusing on propagation approaches based on Wigner functions and the method of moments technique. The respective propagation methods are exempli... Read More about Stochastic electromagnetic field propagation: measurement and modelling.

Elastodynamics on graphs: wave propagation on networks of plates (2018)
Journal Article
Brewer, C., Creagh, S. C., & Tanner, G. (2018). Elastodynamics on graphs: wave propagation on networks of plates. Journal of Physics A: Mathematical and Theoretical, 51(44), Article 445101. https://doi.org/10.1088/1751-8121/aae1d2

We consider the wave dynamics on networks of plates coupled along 1D joints. This set-up can be mapped onto an extension of wave graph systems studied in, for example, quantum graph theory. In the elastic case, different mode-types (flexural, longitu... Read More about Elastodynamics on graphs: wave propagation on networks of plates.

Total photoionization cross section of planar helium: scaling laws and collision orbits (2018)
Journal Article
Lee, M.-H., Byun, C. W., Choi, N. N., & Tanner, G. (2018). Total photoionization cross section of planar helium: scaling laws and collision orbits. Journal of Physics B: Atomic, Molecular and Optical Physics, 51(18), Article 185001. https://doi.org/10.1088/1361-6455/aad8e2

The total photoionization cross section of planar helium has been calculated up to the single ionization threshold I22 of triple P states. The cross section shows chaotic fluctuations as the energy E approaches the double ionization threshold E=0. By...
