Abstract: A comparison of balanced and unbalanced backward wave %direction
dispersion relations and the constitutive electromagnetic
effective parameters of dielectric constant, %as well as
magnetic
permeability are obtained. In the balanced case, the initial transmission
line lies in left handed (LH) medium and the next %steps of
to
cut-off frequency
of higher order regions transmission line becomes in right-handed (RH)
medium. In the unbalanced case, there are a tiny reject band displays due to
the attenuations. It is also desirable for
%left handed
metamaterial
parameters extraction properties should behave in antiresonance behaviour in
the band gap regions. The proposed extraction technique shows the suitable
results for dual negative magnetic permeability and electric permittivity
that match with the theory. To demonstrate the infinite wave investigations,
there are four unit cell of complementary split-ring resonators (CSRRs)
microstrip implementation is obtained and the equivalent lumped element
circuit is analyzed. The theory and experiment result exhibits excellent
agreement that ensures minimum loss and electrical small size due to less
than wavelength dimensions.
