We determine the optical response of a thin and dense layer of interacting quantum emitters. We show that, in such a dense system, the Lorentz redshift and the associated interaction broadening can be used to control the transmission and reflection spectra. In the presence of overlapping resonances, a dipole-induced electromagnetic transparency (DIET) regime, similar to electromagnetically indu...

The use of atomic media to produce optical delay has predominantly exploited the steep dispersion associated with electromagnetically induced transparency (EIT) [1]. While this can lead to very low group velocities it has a severe bandwidth limitation owing to the narrow spectral range over which the transparency and steep dispersion occur, making delays longer than the pulse width difficult to...

Received ; accepted – 2 – ABSTRACT We investigate the structure of the solar chromosphere and transition region using full Sun images obtained with the Extreme Ultraviolet Imaging Telescope (EIT) aboard the Solar and Heliospheric Observatory (SOHO) spacecraft. The limb seen in the EIT coronal images (taken in lines of Fe IX/X at 171Å, Fe XII at 195Å and Fe XV at 284Å) is an absorption limb pred...

An approach to broadband cloaking of light waves is analysed for a simplified case of a scaling transformation for a general cylindrical coordinate system. The proposed approach requires metamaterials with specifically engineered dispersion. The restriction on the signs of gradients in the dispersion dependencies of the dielectric permittivity and the magnetic permeability for different operati...

This paper presents EIT-based fabric sensors that aim to provide a pressure mapping using the current carrying and voltage sensing electrodes attached to the boundary of the fabric patch. Pressure-induced shape change over the sensor area makes a change in the conductivity distribution which can be conveyed to the change of boundary current-voltage data. This boundary data is obtained through e...

This studio explains the application through the application of the ProKEx architecture is used to improve the process of allocation of funding at the European Institute of Innovation and Technology (EIT). The mission of the EIT is to grow and capitalize on the innovation capacity and capability of actors from higher education, research, business and entrepreneurship from the EU and beyond thro...

This paper presents a new image reconstruction technique for 3D EIT based on the extension of the 2D GREIT method. Key aspects include the expansion of optimization targets and set of desired images to cover multiple planes. Results show the reduction off-plane interference seen in 2D reconstruction. The selection of target planes is also found to be highly significant to the image.

A graph G* is l-edge fault tolerant with respect to a graph G, denoted by I-EFT( G), if any graph obtained by removing an edge from G’ contains G. A l-Em(G) graph is said to be optimal if it contains the minimum number of edges among all I-EFT( G) graphs. Let Gf be 1 -EJ!T( Gi) for i = 1,2. It can be easily verified that the Cartesian product graph G; x G; is l-edge fault tolerant with respect ...
