Lens spaces arise from free periodic maps on odd-dimensional spheres. They admit free involutions. We show that if the period of the map is odd, the mod two invariants of such involutions are very much like those of the antipodal map on the sphere, both for single lens spaces and for bundles of lens
Scanning spherical lens antennas are typically constructed using concentric dielectric shells with external primary feed. A cover layer may also be used. A modal expansion method is reported whereby the scattering matrix of this structure is derived and which accounts for both internal and external
