Abstract :
In this study, we characterized left-handed (LH) traveling-wave field effect transistors (TWFETs) for achieving amplification of LH waves. We performed measurements of a test device and observed that attenuation of LH waves propagating along the electrode lines is successfully compensated for. The potential of LH TWFETs can cover the microwave applications, when implemented on printed-circuit boards or integrated circuits. This paper briefly reviews design criteria of LH TWFETs and describes experimental observations, together with calculated performance of the device.
