Abstract :
This letter analyzes scattering properties of spheres with DB boundary conditions. The DB condition is defined by the requirement that the components of electric and magnetic flux densities normal to the boundary are zero. Rayleigh scattering, Mie scattering, and method-of-moments (MoM)-based computations are applied to the problem. The most interesting results are vanishing backscattering and rotational symmetry of the scattering diagram.
