The Reflection Properties of Multilayer Anti-counterfeiting Optical films for Vertical-polarized Wave
Based on the difference of phase-shift direction and amplitude attenuation direction when the optical wave propagates in conductive medium , with the solution of the wave equation and the boundary conditions of optical wave at the interface of the media, the recurrence formula of thevertical-polarized inhomogeneous optical wave in the multilayer film were derived. In order to exammine the reliability of this method, the light energy reflectivity for an 11-layer combinational film was computed, and the compare of calculating results with the existing calculating method was given. The result shows that the reflection properties of light energy reflectivity get good consistency, but the calculated result with this method displays that metal film has stronger absorbing properties and reflection effective of narrow band.
