In addition to
the TEM mode solution, other modes exist in the parallel-plate waveguide.
Assume that the waves propagating in the parallel-plate waveguide have a phase term
,
the 
operator can be decomposed into
components in the 
direction and perpendicular to the direction, namely,
where 
.
Similarly, the fields can also be decomposed into two components as 
and 
.
