Today's tech savvy young learners are equipped with a variety of technological tools used as easily as pencils and paper. Many reach for the laptop first when it's time to write or look for an ebook when it's time to read. Ebooks are increasingly viewed as an appropriate source for literacy exposure to books and reading by parents and educators, as net sales revenue from ebooks surpassed hardcover...
Interference is an important performance limiting factor in cell-based mobile communication scenarios. Especially entities located at cell edges significantly suffer from inter-cell interference caused by base stations serving users in neighboring cells. The standard of LTE considers a frequency reuse factor of one, which makes inter-cell interference coordination a widely discussed topic. However,...
Coordinated transmission between base stations is one of the techniques under investigation to further improve the system performance of E-UTRA. In general, such a coordination, sometimes also called network MIMO, requires a large amount of signaling between cells. A relatively simple scheme for cell coordination is macro diversity. In this paper we consider macro diversity for the downlink direction...
Second harmonic generation (SH) based on the enhancement of localized fields confined in nanoscale periodic, GaAs-filled holes in a metal film is presented. The SH saturates for a fundamental peak power intensity Gt 20 GW/cm2.
Second-harmonic generation without the need for phase matching from a nanopatterned isotropic nonlinear material located inside the subwavelength gaps of a metallic coaxial array is reported. Numerical simulations are in good agreement with experimental data.
