This letter examines the performance of the wavenumber-division-multiplexing (WDM) scheme for parallel spatially-continuous electromagnetic segments, considering different digital processing architectures. The study demonstrates that WDM performs well even when the electromagnetic segments have arbitrary orientations and positions.
This letter considers the wavenumber-division-multiplexing (WDM) scheme that was recently presented by Sanguinetti et al. (2022) line-of-sight communications between parallel (i.e., side-by-side) 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 Sanguinetti et al. (2022) can be particularized to the case of interest and then use numerical results to evaluate the impact of geometric 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 to each other.
