Self-focusing and envelope pulse generation in nonlinear magnetic metamaterials
I. Kourakis, N. Lazarides, G. P. Tsironis
The self-modulation of waves propagating in nonlinear magnetic metamaterials is investigated. Considering the propagation of a modulated amplitude magnetic field in such a medium,…
Quantitative two-dimensional shadowgraphic set-up for high-sensitivity measurement of low-density laser-plasmas
Amrutha Gopal, Stefano Minardi, Michael Tatarakis
We present a quantitative shadowgraphic method which can measure the density of a laser-generated plasma in air with sensitivity and resolution comparable or better than traditiona…
A deep mosaic of [O III] 5007 A CCD images of the environment of the LBV star P Cygni
P. Boumis, J. Meaburn, M. P. Redman +1
A mosaic of six, deep, CCD images in the light of the [O III] 5007 A nebular emission line has been obtained with the 1.3-m Skinakas (Crete) telescope of the filamentary nebulosity…
Discrete breathers in nonlinear magnetic metamaterials
N. Lazarides, M. Eleftheriou, G. P. Tsironis
Magnetic metamaterials composed of split-ring resonators or type elements may exhibit discreteness effects in THz and optical frequencies due to weak coupling. We consider a mo…
New Planetary Nebulae in the Galactic Bulge region with l>0deg - II
P. Boumis, S. Akras, E. M. Xilouris +4
The presentation of new results from an [O III] 5007 A survey in a search for planetary nebulae (PNe) in the galactic bulge is continued. A total of 60 objects, including 19 new PN…
