Query: Performance analysis of WDM in LoS communications with arbitrary
  orientation and position   This letter focuses on the wavenumber-division-multiplexing (WDM) scheme that
was recently proposed in [1] for line-of-sight communications between parallel
spatially-continuous electromagnetic segments. Our aim is to analyze the
performance of WDM, combined with different digital processing architectures,
when the electromagnetic segments have an arbitrary orientation and position.
To this end, we first show how the general electromagnetic MIMO (multiple-input
multiple-output) model from [1] can be particularized to the case of interest
and then use numerical results to evaluate the impact of system parameters
(e.g., horizontal and vertical distances, azimuth and elevation orientations).
It turns out that WDM performs satisfactorily also when the transmit and
receive segments are not in boresight direction of each other.
