The Negative π/2 Phase Shift of Total Reflect Light
Traveling light is totally reflected on boundary, the evanescent wave intensity exhibits exponential decay with distance from the boundary at which the wave was formed. In this paper, we do theoretical analysis of the total reflected light phase shift and power value of the evanescent wave was “disturbed” by the other objects. A marvelous optics phenomenon is the -π/2 phase shift of reflected light.
