[′grēnz dī′ad·ik]

(mathematics)

In addition, as far as the Green's dyadic is numerically computed in the source (nanostructures) region, all the electromagnetic properties of the system are easily obtained with practically almost no additional computing cost [12].

Another notable advantage of this approach is that it considerably reduces the memory cost for evaluating the Green's dyadic. Finally, different mesh shapes can be considered by adapting the integral surface.
