Figure 16

Magnitude of the electric field, in volts/meter, within the inhomogeneous plasma cylinder obtained by the FDTD simulation for different collision frequencies ν. Incident wave frequency is set to f_in = 10 GHz, and central electron density is set to n₀ = 5 × 10¹⁷ m⁻³.

(a) ν = 500 × 10⁶ Hz

(b) ν = 500 × 10⁷ Hz

(c) ν = 500 × 10⁸ Hz
