Microwave propagation experiments on a waveguide loaded by an array of split-ring resonators

A study of split-ring resonators with different arrays containing two, four and six cells is conducted experimentally to verify the transmission band resulting from the electrical and magnetic responses of the metamaterial array. Microwave propagation below cutoff in an X-band waveguide loaded with an array of split-ring resonators is demonstrated. Transmission bands corresponding to magnetic and electrical frequencies are measured and compared with simulation model with good agreement.
