dc.description.abstract | In this Letter we demonstrate that the dispersion properties associated with glide symmetry can be achieved
in systems that only possess reflection symmetry by balancing the influence of two sub-lattices. We apply
this approach to a pair of coupled slots cut into an infinite perfectly conducting plane. Each slot is notched
on either edge, with the complete two-slot system having only mirror symmetry. By modifying the relative
size of the notches on either side of the slots, we show that a linear dispersion relation with a degeneracy
with non-zero group velocity at the Brillouin zone boundary can be achieved. These properties, until now,
only found in systems with glide symmetry are numerically and experimentally validated. We also show that
these results can be used for the design of ultra-wideband one-dimensional leaky wave antennas in coplanar
waveguide technology. | en_GB |
