A double-negative (DNG) material based on dielectric particles is experimentally analyzed.
The DNG material is assembled using ceramic particles with high dielectric constant, and a
conducting wire frame. The ceramic particles contribute to the effective negative permeability
thanks to Mie resonance, while the conducting wire frame provides the effective negative
permittivity. The measured transmittances are in good agreement with the theoretical
prediction. The influence of the particle shape and distribution on the effective negative …
