Evolution of the disk of pi Aqr: from near-disappearance to a strong maximum
Y. Naze, G. Rauw, J . Guarro Flo +30
Some Be stars display important variability of the strength of the emission lines formed in their disk. This is notably the case of pi Aqr. We present here the recent evolution of…
Kerr principal null directions from Bel--Robinson and Kummer surfaces
Jens Boos, Alberto Favaro
In the Kerr geometry, we calculate various surfaces of constant curvature invariants. These extend well beyond the Kerr horizon, and we argue that they might be of observational si…
Plane-Wave Propagation in Extreme Magnetoelectric (EME) Media
I. V. Lindell, A. Sihvola, A. Favaro
The extreme magnetoelectric medium (EME medium) is defined in terms of two medium dyadics, , producing electric polarization by the magnetic field and , producing magnetic po…
Electromagnetic wave propagation in metamaterials: a visual guide to Fresnel-Kummer surfaces and their singular points
Alberto Favaro
The propagation of light through bianisotropic materials is studied in the geometrical optics approximation. For that purpose, we use the quartic general dispersion equation specif…
Light propagation in local and linear media: Fresnel-Kummer wave surfaces with 16 singular points
Alberto Favaro, Friedrich W. Hehl
It is known that the Fresnel wave surfaces of transparent biaxial media have 4 singular points, located on two special directions. We show that, in more general media, the number o…
Optimal Frames for Polarisation State Reconstruction
Matthew R. Foreman, Alberto Favaro, Andrea Aiello
Complete determination of the polarisation state of light requires at least four distinct projective measurements of the associated Stokes vector. Stability of state reconstruction…
