As in the case of a finite system, eq.
can be written in a shorter block-matrix form,
\begin_inset Formula
\[
\left(I-WT\right)\outcoeffp{\vect 0}\left(\vect k\right)=\rcoeffincp{\vect 0}\left(\vect k\right)
\]
\end_inset
Eq.

\end_inset
can be used to calculate electromagnetic response of the structure to external
quasiperiodic driving field – most notably a plane wave.
However, if one sets the right the right-hand side to zero, it can also
be used to find electromagnetic lattice modes
