                         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.",
