Free-electron lasers (FELs) are fourth-generation light sources that deliver extremely high intensity, ultrashort pulses over a broad wavelength range from far-infrared to hard x ray. FELs based on the self-amplified spontaneous emission principle have been successfully operated with ultrahigh brightness and wavelengths tuning good transverse coherence but poor temporal coherence. In contrast, laser-seeded provided full at selected central wavelengths, usually harmonics of laser seeds,...
GPS positioning data are increasingly utilized in environmental behavior studies to explore the spatial-temporal behavioral patterns of individuals. However, individuals' stay pattern and its influencing factors, which particularly significant for design management scenic architectural complexes, have not been thoroughly examined. Using trajectory collected from Palace Museum Beijing (China), this paper investigated visitors' associated with temporal, spatial, factors. Types characteristics...
Optimization of a terahertz broadband tabulate metamaterial absorber is presented. We apply the hybrid optimization algorithm, which composes differential evolution stratega and continuous anìt colony optimization, to optimize bandwidth absorbing metamaterial. Numerical results show that optimized has 0.103THz for absorptance above 90%.
