Abstract  We propose a new class of negative refractive index transmission line in which ideal operational amplifiers are applied to form the periodically loaded negative-impedance-converted inductors and capacitors. The phase response of the new transmission line is opposite to that of a positive refractive index conventional transmission line. Unlike the existing negative refractive index transmission line, the new negative refractive index transmission line is non-dispersive and thus can lead to many novel applications such as designing new broadband devices.

Key words： Negative refractive index (NRI)      Transmission line (TL)      Negative-impedance-converted      Non-dispersive
