| Abstract: | A method based on reflective mesoscopic spectroscopy for characterization of refractive-index fluctuations at nano-scale is introduced.Mechanism of mesoscopic spectroscopy for perceiving reflective-index fluctuations at length scale of nanometers is revealed.Based on simulation by finite difference time domain method,light propagation in one-dimensional refractive-index variable medium and resulting reflective spectral characteristics are analyzed.Through precise control of standard deviation and spatial co... |
