Geometric interpretation of the 3-dimensional coherence matrix for nonparaxial polarization
M. R. Dennis
The 3-dimensional coherence matrix is interpreted by emphasising its invariance with respect to spatial rotations. Under these transformations, it naturally decomposes into a real…
Local phase structure of wave dislocation lines: twist and twirl
M. R. Dennis
Generic wave dislocations (phase singularities, optical vortices) in three dimensions have anisotropic local structure, which is analysed, with emphasis on the twist of surfaces of…
Braided nodal lines in wave superpositions
M. R. Dennis
Nodal lines (phase singularities, optical vortices) are the generic interference fringes of complex scalar waves. Here, an exact complex solution of the time independent wave equat…
Correlations and screening of topological charges in gaussian random fields
M. R. Dennis
2-point topological charge correlation functions of several types of geometric singularity in gaussian random fields are calculated explicitly, using a general scheme: zeros of …
