[Getdp] Eigenmodes of a dielectric structure

[Andre Nicolet]

Dear Pablo,

It is most probably my work that you have seen when you talk about band 
structure computation of photonic crystals.
GetDP is probably able to compute your resonances if you write your 
problem in the form of a clean (mathematically speaking) eigenvalue problem.
About the continuity of field components, there should be no problem if 
you use the correct function spaces. Have you heard about edge elements, 
Whitney elements and all that?
Good work!
André
