Description
Yaseman Shiri and co-authors published an engineering paper in 2025 on steering terahertz beams with surface waves on a smart surface. Control of wave fronts in this band serves sensing and communications. Most smart surfaces work with waves in open space, as pass-through or mirror elements. Surface waves that run along the array can strengthen the effect, but few studies use them.
The team placed the surface inside a parallel-plate guide built for the surface-wave layout. Changing the surface's electrical traits shifted the guided wave and so the angle of the beam leaking out of a slot. Results matched computer simulations. The authors present the layout as a new route to broadband beam steering in this range.
