Abstract :
In the paper, a new nonlinear left-handed transmission line (NLHTL) that incorporates arrays of Josephson junctions (JJs) is proposed. The nonlinearity of the newly developed Josephson left-handed transmission line (JLHTL) is due to the highly nonlinear nature of the JJs that provide the shunt inductances required to realise an LHTL. The current-voltage relationship of an array of JJs is utilised to realise an inductively tunable LHTL. Dispersion analysis along with the scattering parameters of the JLHTL are presented to study the left-handed behaviour of the JLHTL. Finally, harmonic generation of the proposed JLHTL is studied
