Figure 5
Analysis of the inverse Doppler effect based on the dynamic FDTD method.
(a) Simulation of light transmitted through the moving PhC at a velocity of 0.05 c. The red dot denotes the position of the detector, the red arrow points in the direction of the emitted light and the blue arrow points in the direction of which the PhC moves. The inset shows the recorded field obtained at the detection point and its Fourier spectrum. (b) Comparison between the detected frequencies fd and the calculated frequencies fc at three speeds: 0.01 c, 0.02 c and 0.05 c.
