强大的计算电磁场本征函数与本征模的程序

10 January 2008

Corrected algebraic error in the expressions for Axy(E),
Axy(W), Ayx(N) and Ayx(S). The earlier version was only correct
in the special case when e=w and n=s. (I.e., when the mesh is
uniform in the vicinity of the dielectric edges.) Many thanks
to [e-mail], who pointed out this bug. The
corrected expressions now agree with the isotropic equations of
Lusse et al, in limit that the materials are isotropic.
