Abstract

Scalability of the photo-injected Fresnel zone plate technique for adaptive beam forming and non-mechanical steering to higher sub-mm wave frequencies is discussed. This method proves to be an attractive option for a range of applications,
where at higher frequencies larger F/D ratios are shown to yield optimal performance, with marginal increases in required irradiation densities. Experimental data is also presented at 94 GHz using a simple, low cost, and highly flexible architecture, highlighting the potential benefits of this technology.
