Abstract

We introduce active negative-index metamaterials based on left-handed nonlinear transmission line media and measure a greater than 10 dB amplification of a weak signal wave at the output of the transmission line due to its parametric interaction with an intensive pump wave, by which energy in a pump wave at one frequency is transferred to the energy in a weak signal wave at another frequency.
