Evolution of Frequency Selective Surfaces

This review gives an account of the route through which Frequency Selective Surfaces have developed in form and in application over the past few decades. Applications range from their use in radome structures, and in meta-materials, to their incorporation into buildings for signal propagation control

in the built environment. For some of these applications the geometries of the array elements can be very simple, but in cases where surfaces are curved, significantly more complicated configurations are likely to be required. Fabrication cost is an important issue. In applications to multiband radiometry for satellite systems for example, the high cost of precision manufacture is normally considered to be acceptable. In contrast, in the built environment inexpensive larger scale production techniques are important. Inkjet or 3D printing may offer cost effective ways forward.
