Abstract : In this work we describe the use of laser direct-write for the rapid prototyping of frequency selective Fresnel zone plate lenses. We describe a frequency selective surface which is patterned on two distinct length scales; a smaller scale that exhibits the patterning of a traditional frequency selective surface, and a larger scale that exhibits the structure of a Fresnel zone plate. We demonstrate that laser direct-write is an ideal tool for the rapid prototyping of such spatially varying or a periodic electromagnetic structures. We present experimental results for the electromagnetic characterization of a prototype frequency selective lens fabricated using non-lithographic, laser processing.
