abstract = "A study of a non-uniform metamaterial array consisting of six
split-ring resonators of varying diameters is conducted
experimentally to measure the transmission and reflection
characteristics that arise from asymmetry in the longitudinal
direction. Such characteristics are examined and compared with
their counterpart symmetric scattering coefficients associated
with a uniform split-ring array. In the non-uniform array the ring
diameters vary in steps of 0.5 mm, which yields a gradient
geometry. Inserting the non-uniform array in an X-band waveguide
operating below cutoff provides a transmission band wider than
that obtained from the uniform array. Different from the uniform
array, for which the magnetic resonance frequency is on the left
and away from the electric resonance frequency, in the gradient
array the magnetic response lies inside the electric band.",
