Future cellular mobile radio networks will exhibit a much more dense base station deployment than 2nd or 3rd generation communications systems, particularly with regard to traffic coverage.
Essential to the construction of micro-mechanical systems is the ability to manufacture micro-mechanical components.
Using silicon etching techniques, free-standing micro gears and turbines were fabricated from silicon.
Essential to the construction of micro-mechanical systems is the ability to manufacture micro-mechanical components.
Robots bring to mind and are, for the most part, electromechanical systems on the scale of human beings.
This paper addresses the issue of micro-cells planning within macro-cell using a single UMTS carrier.
Local electronic states due to characteristic surface islands and pits formed on an atomically flat (110) GaAs interface of a quantum well fabricated by a cleaved-edge-overgrowth method with high-t
Micro-photoluminescence (PL) and micro-PL excitation (PLE) spectra were measured systematically in a 5 nm GaAs/AlAs single quantum well (QW) to investigate the predicted effect of asymmetric excito
Micro-Raman scattering measurements were used to study the phonon modes and to analyze the local variation of composition and strain in the micron range of AlxGayIn1-x-yAs materials grown in the re
Many integrated photonics applications require miniaturized on-chip sources over a wide wavelength range, such as coherent optical communication and spectroscopy.
