摘要
基于打靶法和光束传播法,用MATLAB数值模拟了光折变晶体界面局域表面波的形成和稳定性。结果表明,传播常数增大时,波模的横向宽度变小,局域表面波的振幅与能量单调递增。而且,局域表面波可在线性电介质与光折变晶体界面稳定传播。
Based on the shooting method and the beam propagation method,we investigate numerically the generation and stability of localized surface waves(LSWs)near the boundary of photorefractive crystal using MATLAB.The results show that,with an increase in the propagation constant,the transverse width of LSWs decrease,the amplitude and energy of LSWs increase.Moreover,LSWs can propagate stably along the interface between a linear dielectric and photorefractive crystal.
