Broadband suppression of backscattering at optical frequencies using low permittivity dielectric spheres
The exact suppression of backscattering from rotationally symmetric objects requires dual symmetric materials where ε (r) = μ (r). This prevents their design at many frequency bands, including the optical one, because magnetic materials are not available. Electromagnetically small non-magnetic spher...
