Abstract: Left handed materials (LHM) take the attention of researchers in various domains in the
electromagnetic spectrum due to the exciting new possibilities that do nno exist in natural materials. The electromagnetic behavior of these materials allows having permittivity and/or permeability with
negative real parts. In this paper we will investigate two designs of LHM in the W-band range (70뀸
GHz). The LHMs under study are double-negative materials (DNG) composed of various configurations
of split ring resonators (SRR) in combination with wire structures. CST MICROWAVE STUDIO is used
to simulate the left handed materials. The electromagnetic fields have been monitored at different
frequencies from a single simulation. Moreover the complex permittivity and permeability are retrieved
from the S-parameters for the whole W-band.
