In this paper a new volumetric three dimension metamaterial design has been
proposed. The structure consists of spherical balls of stainless steel and substrate of
Bakelite. The structure is simulated from 1 to 20 GHz and show negative refractive in this
range. Reflection and transmission coefficient (s-parameter) is used to calculate the
effective permittivity and permeability of the structural. Refractive index of the structure
is then calculated using effective permittivity and permeability of the structural. Due to
negative refractive index it exhibits several unusual properties like focusing of light even
with flat surfaces. This material can be easily incorporated with microstrip antennas to
get highly directional beam patterns by using it as a substrate.
