Finite-Difference Time Domain Techniques Applied to Electromagnetic Wave Interactions with Inhomogeneous Plasma Structures

Figure 3

Total-field scattered-field technique used to generate the incident fields and calculate the scattered far fields.

(a) Region separation for the TFSF technique. Region 1 consists of total fields while region 2 consists only of scattered fields

(b) Detailed view of the field components adjacent to the TFSF boundary. A computational cell at the corner of the TFSF boundary is shown
