Optics undergraduate experiments using smart (and not so smart) phones
V. L. Díaz-Melián, L. A. Rodríguez, F. Pedroso-Camejo +4
Smartphones may be seen as miniature toolboxs to perform Physics experiments. In this paper, we present three different "optics workbenches" mainly based on the light meter of a sm…
Electrically Small Supergain Arrays
Arthur D. Yaghjian, Terry H. O'Donnell, Edward E. Altshuler +1
The theory, computer simulations, and experimental measurements are presented for electrically small two-element supergain arrays with near optimal endfire gains of 7 dB. We show h…
On the interpretation of "off the edge" avalanches
O. Ramos, A. J. Batista-Leyva, E. Altshuler
We establish both experimentally and theoretically the relation between off the edge and internal avalanches in a sandpile model, a central issue in the interpretation of most expe…
