Abstract :
We introduce active negative index metamaterials based on left-handed nonlinear transmission line media, and measure for the first time the amplification of a weak signal wave at the output of the transmission line due to its parametric interaction with an intensive pump wave in these media, by which energy in a pump wave at one frequency is transferred to energy in a weak signal wave at another frequency
