Abstract

An aplanatic lens backed by an offset conductive bowl was found to satisfy the ISO8729 passive RCS enhancer requirements in a 12GHz scaled model across ±15°. Here the effects of permittivity on 4λ0 radius lens weight, focal arc angular spread and position were studied in simulation at 9.41GHz for f/D=0.9. Increasing permittivity decreased lens weight. Cutting a circular lens to a square reduced the focal arc and angular spread. A novel lens consisting of a dielectric rod with 2 concentric toroids increased the focal peak from 6V/m to 6.6V/m and decreased the plastic mass from 1.7kg to 1.2kg, but will require an aerogel or foam support.
