The authors analyze the effect of bichromatic microwave irradiation on the magnetoresistivity of a two dimensional electron system. The authors follow the model of microwave driven Larmor orbits in a regime where two different microwave lights with different frequencies are illuminating the sample (w1 and w2). The authors’ calculated results demonstrate that now the electronic orbit centers are driven by the superposition of two harmonic oscillatory movements with the frequencies of the microwave sources. As a result the magnetoresistivity response presents modulated pulses in the amplitude with a frequency of (w1−w2)∕2, whereas the main response oscillates with (w1+w2)∕2.
