We demonstrate that optomechanical non-reciprocity is equivalent to the\nanti-resonance, often discussed in the context of coupled driven harmonic\noscillators. We show that that suitable phase-difference between the cavity\ndriving fields make the relevant optomechanical couplings complex, which leads\nto non-reciprocity in the field fluctuations and anti-resonance in average\nfield amplitudes. This analogy with anti-resonance demonstrates that only for a\nparticular frequency (the so-called isolation frequency) of input signal,\nmaximum non-reciprocity can be achieved. In contrast to the previous studies,\nwe here show that one can dynamically control this isolation frequency by\napplying a mechanical drive of suitable frequency to the membrane in the\noptomechanical setup.\n
