A new class of negative refractive index transmission line
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
