Main Results:

A surface mode with a negative slope was identified in the dimer-layer.
Directive, backward radiation was observed due to leaky mode coupling.
Beam steering over a 70-degree range was achieved between 11.88-13.69 GHz.
Experimental results agreed with FDTD simulations.

Conclusions:

A PC-based surface wave structure acts as a frequency-dependent leaky wave antenna.
The structure supports backward leaky modes, enabling backward radiation.
The demonstrated beam steering and directive radiation have potential applications in advanced antenna systems.
