Optimized terahertz-wave generation using BNA-DFG.
An effective and widely tunable means of producing terahertz (THz) radiation using difference-frequency generation (DFG) in an organic N-benzyl-2-methyl-4-nitroaniline (BNA) crystal was demonstrated by optimizing the pump wavelengths. We calculated the (wideband) refractive index and coherence length mapping of BNA to establish the optimum phase-matching condition of the DFG configuration. To s...
متن کاملObservation of Shear Wave Generation at Bonded
The drive toward higher efficiencies and performance in energy production and transportation equipment has posed a continual challenge for the materials scientists and engineers involved in design and construction of such equipment. The laws of thermodynamics specify that increased efficiency can best be achieved by the use of the highest possible temperatures. As the desired operating temperat...
متن کاملWave-packet dynamics by optimized polynomials methods
An optimized and numerically stable method, based on the formalism of orthogonal polynomials, is proposed to solve the time-dependent Schrödinger equation and to construct energy-filtered wave-packets. It is compared to other methods (Runge-Kutta, Second-Order Differencing scheme). A method is also devised to study quantum diffusion in finite systems with periodic boundary conditions, which all...
متن کاملHybrid Beamforming for 5G Millimeter-Wave Multi-Cell Networks
Multi-cell wireless systems usually suffer both intracell and inter-cell interference, which can be mitigated via coordinated multipoint (CoMP) techniques. Previous works on multi-cell analysis for the microwave band generally consider fully digital beamforming that requires a complete radio-frequency chain behind each antenna, which is less practical for millimeterwave (mmWave) systems where l...
