comment Overlap function of three modes
Yes, I understand that much. Note that the overlap of u and v are weighted by their mutual overlap with (the z-component of) w on the surface. It's a bit hard to pin down what my actual question is, but I think it has two parts: (1) is this "dot product of three vectors" a recognizable thing in mathematics with desirable properties? If so, why have I never seen it before, unlike the case with just 2 vectors. And, (2), how do I know this is the correct normalization?

comment Etymology of the word “pole”?
Yes, I guess the word 'pole' is probably related to its usage in monopole, dipole, ..., multipole, etc.

@lhf What do you mean by 'electric pole'? a point charge?
