Coupling of unstructured TLM and BEM for accurate 2D electromagnetic simulation (2015)
Conference Proceeding
Simmons, D., Cools, K., & Sewell, P. (2015). Coupling of unstructured TLM and BEM for accurate 2D electromagnetic simulation.

In this paper the hybridisation of the 2D time-domain boundary element method (BEM) with the unstructured transmission line method (UTLM) will be introduced, which enables accurate modeling of radiating boundary conditions and plane wave excitations...

Modelling antennas in outer space using the boundary element unstructured transmission-line (BEUT) method (2015)
Presentation / Conference
Simmons, D., Cools, K., & Sewell, P. (2015, October). Modelling antennas in outer space using the boundary element unstructured transmission-line (BEUT) method. Paper presented at 36th ESA Antenna Workshop on Antennas and RF Systems for Space Science, Noordwijk, Netherlands

In this paper the hybridization of the 2D time domain boundary element method (BEM) with the unstructured transmission line method (UTLM) is described. The novel method enables accurate modelling of radiating boundary conditions, excitation by plane...

Threshold manipulation in parity-time symmetric microresonator chain (2015)
Conference Proceeding
Phang, S., Vukovic, A., Creagh, S., Benson, T. M., Gradoni, G., & Sewell, P. D. (2015). Threshold manipulation in parity-time symmetric microresonator chain.

This paper analyses the eigenfrequencies of an infinitely long chain of microresonators with PT symmetry. The results show that the depth of modulation of the real part of the refractive index can be used to control the threshold point of the PT stru...

Parity-time chain of whispering-gallery mode resonators (2015)
Conference Proceeding
Phang, S., Vukovic, A., Creagh, S., Benson, T. M., Gradoni, G., & Sewell, P. D. (2015). Parity-time chain of whispering-gallery mode resonators.

The paper analyses the dispersion characteristics of an infinitely long PT chain made of whispering gallery resonators with gain/loss modulation. The results show that the appearance of the threshold breaking point depends not only on both of couplin... Read More about Parity-time chain of whispering-gallery mode resonators.

Modeling curved carbon fiber composite (CFC) structures in the transmission-line modeling (TLM) method (2015)
Journal Article
Meng, X., Sewel, P., Phang, S., Vukovic, A., & Benson, T. (2015). Modeling curved carbon fiber composite (CFC) structures in the transmission-line modeling (TLM) method. IEEE Transactions on Electromagnetic Compatibility, 57(3), 384-390. doi:10.1109/TEMC.2015.2400055

A new embedded model for curved thin panels is developed in the transmission line modeling (TLM) method. In this model, curved panels are first linearized and then embedded between adjacent 2-D TLM nodes allowing for arbitrary positioning between adj...

A versatile all-optical parity-time signal processing device using a Bragg grating induced using positive and negative Kerr-nonlinearity (2015)
Journal Article
Phang, S., Vukovic, A., Benson, T. M., Susanto, H., & Sewell, P. (2015). A versatile all-optical parity-time signal processing device using a Bragg grating induced using positive and negative Kerr-nonlinearity. Optical and Quantum Electronics, 47(1), https://doi.org/10.1007/s11082-014-0012-2

The properties of gratings with Kerr nonlinearity and PT symmetry are investigated in this paper. The impact of the gain and loss saturation on the response of the grating is analysed for different input intensities and gain/loss parameters. Potentia...
