Transduction of magnetoinductive waves (MIWs) in planar technology is demonstrated. A
transducer consisting of a one-dimensional periodic array of metallic split squared ring resonators
(SSRR), placed between a pair of microstrip lines on a planar substrate has been fabricated and
measured. The microstrip lines are inductively coupled to the SSRRs located at the ends of the
periodic array and excite MIWs that propagate along the array. The theoretical model for the
dispersion of MIWs is used to predict the dispersion relation and the delay time in the device. The
delay time was measured and a good agreement was found with the theoretical predictions. The
transmission coefficient of the device was also measured. The theoretical and experimental results
suggest that the proposed configuration can find application in the design of delay lines and other
microwave devices. In fact, the behavior of the proposed transducer is similar to that of the
conventional ferrite magnetostatic-wave transducer. However, ferrite devices are fragile, difficult to
integrate, and require a heavy external magnet or electromagnet to magnetize the ferrite to
saturation. Since all these drawbacks are not present in the proposed configuration, it may be a
useful alternative to those devices for many practical applications. [--]
