Q UARTZ is one of the commonest of crystalline minerals and occurs in many variations of size, color, purity, and structural perfection.
Correlated and uncorrelated transverse displacements of the lenses of a beam-waveguide 1 2 3 4 5 cause a propagating light beam to deviate from the axis of the guide.
Architects calculate the reverberation time of a room from one of four simple approximate formulas (Sabine, Eyring, Millington, Kuttruff).
In this paper, the properties and capabilities of 3D beamforming in a real propagation scenario have been analyzed by ray tracing simulation and been compared with field measurements for this envir
Elevation spread of departure angles (ESD) is the key parameter characterizing a 3D fast-fading channel model.
A system is presented that combines the progressive refinement radiosity algorithm with a production ray tracing system.
In this paper, the propagation for 3GPP high speed train (HST) scenarios is studied both at 30 GHz and 3.5 GHz.
Rayleigh crosstalk caused by the double Rayleigh reflection of a signal is investigated in long systems consisting of distributed Raman amplifiers.
The term "Rayleigh scattering" describes light scattering from refractive index inhomogeneities whose linear dimensions are much shorter than the wavelength of light.
Recent results demonstrated that the capacity of installed transmission systems can be upgraded by means of Raman gain with minor changes at the receiver terminal and, most importantly, no changes
