Cherenkov Emission Generated by a Modulated Source in 2D Dispersive Photonic Crystal Slabs
Figure 8
(Color on line) snapshots the field in plane for particle moving with (a)-(b) and (c)-(d) . (a) Field for , the Cherenkov cone is well defined with oscillations in the path of the charge. (b) Field for , the Cherenkov emission is observed, with a lower number of oscillations than subsection (a) due to the modulation of the source. (c) , oscillations in the path of the charge; however, in this case, we did not observe the group cone. (d) Cherenkov group cone for and .
