Autor: Carlos A. Viteri-Mera, Fernando L. Teixeira

Publikováno v: IEEE Access, Vol 5, Pp 3944-3957 (2017)

Time-reversal (TR) is a beamforming technique for wireless frequency-selective channels, which has received increasing attention due to its high energy efficiency and low computational complexity. In this paper, we present two contributions on TR bea

Publikováno v: Nonlinear Analysis, Vol 9, Iss 3 (2004)

We study numerically and experimentally self-focusing dynamics of femtosecond light pulses. By demonstrating the potential of three dimensional imaging technique for quantitative recovery of complex (arbitrarily shaped) wave packets, we monitor space

This thesis consists of two independent parts. In the first one, we consider a reference medium, containing some scatterers whose positions are unknown. Using an array of transducers, our goal is to generate an acoustic wave that would focus in space
