very fast implementations are available. In this way, all operations are diagonal
and the memory required is of the order of the number of expansion coefficients,
rather than the square of this n umber. The linear operator in Eqn (20.13) turns out
to be Hermitian, and so the actual eigensolutions can be obtained in a Rayleigh–
Ritz fashion by minimizing the functional hHðxÞj
^
jHðxÞi=hHðxÞjHðxÞi. Typi-
cally, this is done using a standard algorithm such as conjugate gradients or more
sophisticated variants [26]. The vast majority of plane wave calculations in the last
15 years have being performed with this approach. Extensions to include aniso-
tropy and improve the moderate convergence properties associated with PWE of
discrete jumps in refractive ...
