Cherenkov Emission Generated by a Modulated Source in 2D Dispersive Photonic Crystal Slabs

Figure 3

Frequency calculated numerically for different values of in a slab of holes for radius and 0.35. It is seen that for a greater contrast of the dielectric constant, the value of the decreases, until reaching the minimum value in for and the maximum for . The graph inside the panels show the case of for where the red curve is the experimental data, while the blue one shows the results following from the equation . See more details in text.
