... The number of points 3d − 1 that appears in this formula is the critical number of points for this problem; if this was less the answer would be infinite, if it was more the answer would be zero. We now have now a well defined problem, but simple questions may have deceptively complicated solutions. ...

Notes on total internal reflection and waveguides
... 0 limit, which are very tricky to integrate (in practice, one just bounds the integrals). The analogous problem for waveguides is a 3d waveguide in which the solutions are localized in two transverse dimensions (e.g. xy), and again it turns out that there is indeed a guided mode for every k 6= 0, bu ...
