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
