In this paper, the nonlinear single negative metamaterials (NLSNM) based on the microstrip loaded with varactor diodes are investigated. It is found that the NLSNM, including nonlinear epsilonnegative metamaterial (NLENM) and nonlinear mu-negative metamaterial (NLMNM) can be realized by loading varactor diodes and chip inductors onto the microstrip, and their transmission gaps can be controlled conveniently by the signal power. In addition, the nonlinear property of the heterostructure

The NLSNM may have important potential applications in the microwave switch controlled by the signal power.
