Hello all, I am currently doing a project where I am working on dyadic green's functions for an electromagnetic problem. My question comes in on how to handle the dyadic in mathematica with the dot product of the source. Currently I create the dyadic using my N(x,y,z) and M(x',y',z') as: [...] KroneckerProduct[Nemn[m, n, x, y, z, kg[m, n]],Memn[m, n, xp, yp, zp, - kg[m, n]]] [...] This creates the correct dyadic for my problem. My issue comes in on how to handle the source integral: Integrate[ Gp[x,y, z, xp, 0, zp] .MoA[xp], {xp, a/2, a}, {zp, -d/2, d/2}] + Integrate[ Gp[x, y, z, a, yp, zp].MoB[yp], {yp, 0, b}, {zp, -d/2, d/2}] + Integrate[ Gp[x, y, z, xp, b, zp].MoC[xp], {xp, a, a/2}, {zp, -d/2, d/2}] Am I missing something fundamental on how to handle the source integral? Is Dot[] the correct function to use here? Thank you in advance, Jason
