  Hello.
  I analyzed a graphene waveguide in FDE solver. Then I got the confinement factor value. Why is the confinement factor value negative? What is the cause of this problem? I expect it to be zero, not negative, eventually!
  Thank you

  Graphene is very thin and you are calculating the result through discrete algorithm. such error on the order of -5 is reasonable. I think I have replied you in another post. Please be patient and only post your questions in one Forum, English or Chinese. Otherwise the very limited support resources is wasted.
