On the basis of the two-temperature model (TTM), the influence of electronic heat capacity(Ce), electroacoustic coupling coefficient(G) and electron thermal conductivity(Ke) is simulated, contrasted and analyzed by finite element method and method of

In this work, we present a method for generating vector vortex beams with metasurfaces. A Jones calculation is employed to theoretically analyze the phase and polarization transformation from metasurfaces. The experimental results are shown to agree

With the phase screen theory, distribution of light field on the take-over plane is analyzed and simulated after a Gaussian laser beam propagates in the turbulent atmosphere. The square difference of light intensity scintillation is given out, and co

Intensity of atmospheric turbulence may overly affect bit error rate for a ground-based laser wireless communication system, so it is necessary to measure of atmospheric turbulence intensity and fluctuation of image centroid while laser beam propagat

The multiple phase screens and Fourier-transform algorithm for numerical simulation of beam propagation through atmospheric turbulence is important for imaging problems, lidar or laser radar. In this work Fast-Fourier-transform-based model of phase s

Cat-eye effect of opto-electric system plays a important role in the active detection, which was studied by many researchers based on the geometric methods. But in practical application of it on the war field, the laser beam must be affected by the a
