Summary:
Surface waves has been demonstrated to be a good candidate to transmit electromagnetic waves the THz regime. Particularly, it has been proven that surface plasmons, and particularly the named domino plasmons, can be used to create THz circuitry which presents low losses. In addition, these plasmons can be easily laterally confined without mismatch. In this paper, we demonstrate how this technology can be extended to obtain phase delays in waveguides with the inclusion of dielectric slabs in between the corrugated metallic slabs. This proposal can be used to excite arrays of antennas in order to achieve directive radiation patterns with different pointing directions.
