Faraday shield dissipation in the drivers of SPIDER based on electromagnetic 3D calculations

Autor: López-Bruna, D., Denizeau, S., Predebon, I., La Rosa, A., Poggi, C., Agostinetti, P.

SPIDER (Source for the Production of Ions of Deuterium Extracted from Rf plasma) is a full-scale prototype of the ITER NBI source. It is based on the concept of inductive coupling between radio-frequency current drive and plasma. Present three-dimens

Preliminary mapping of ionospheric total electron content (TEC) over Ecuador using global positioning system (GPS) data

Autor: Lopez, Ericson D., Ubillus, Bryan A., Meza, Ariel A.

The ionosphere affects radio signals by altering their speed, direction, and trajectory, causing a temporary delay known as ionospheric delay, which is directly related to the total electron content (TEC). Although research in other equatorial locati

A growth diagram for plasma-assisted molecular beam epitaxy of GaN nanocolumns on Si(111)

Autor: Fernández-Garrido, S., Grandal, J., Calleja, E., Sánchez-García, M. A., López-Romero, D.

Publikováno v: JOURNAL OF APPLIED PHYSICS 106, 126102 (2009)

The morphology of GaN samples grown by plasma-assisted molecular beam epitaxy on Si(111) was systematically studied as a function of impinging Ga/N flux ratio and growth temperature (750-850{\deg}C).Two different growth regimes were identified: compa

Energy efficient cell-free massive MIMO on 5G deployments: sleep modes strategies and user stream management

Autor: Riera-Palou, F., Femenias, G., López-Pérez, D., Piovesan, N., De Domenico, A.

This paper proposes the utilization of cell-free massive MIMO (CF-M-MIMO) processing on top of the regular micro/macrocellular deployments typically found in current 5G networks. Towards this end, it contemplates the connection of all base stations t
