Optical vortices in beam propagation through a self-defocussing medium (1992)
Journal Article
Mcdonald, G., Syed, K., & Firth, W. (1992). Optical vortices in beam propagation through a self-defocussing medium. Optics Communications, 94(5), 469-476. https://doi.org/10.1016/0030-4018%2892%2990589-J

We present numerical simulations and analysis of optical vortex propagation in a 3D self-defocussing medium. On plane wave background initial conditions composed of points and lines of phase discontinuity are shown, in some cases, to evolve towards a...

Hexagon patterns in optical bistability (1992)
Journal Article
Firth, W., Scroggie, A., McDonald, G., & Lugiato, L. (1992). Hexagon patterns in optical bistability. Physical Review A, 46(7), R3609-R3612. https://doi.org/10.1103/PhysRevA.46.R3609

The mean-field model of optical bistability in a ring cavity is extended to include diffraction in two transverse dimensions. Nonlinear analysis in the neighborhood of the instability of the homogeneous solution indicates the formation of stable hexa... Read More about Hexagon patterns in optical bistability.

Narrative structures within architectural videos (1992)
Journal Article
Rhodes, P., McCartney, K., & Powell, J. (1992). Narrative structures within architectural videos. Design Studies, 13(4), 355-378. https://doi.org/10.1016/0142-694X%2892%2990131-S

This paper reports on a research programme concerning the communication of architectural information through the use of video. In recent years, the general public have become increasingly interested in and aware of architecture. This has been at leas... Read More about Narrative structures within architectural videos.
