We extend Green';s function formalism to a three-component network by introducing a difference admittance ratio eta=(epsilon(2)-epsilon(0))/(epsilon(1)-epsilon(0)). Using the formalism, we investigate the dielectric resonance of various disordered composites, and find that the neighboring resonances avoid crossing when parameter eta is varied in the interval etais an element of(0,2]. It is also shown that the geometric disorder and colored disorder lead to the avoiding of crossing of dielectric resonances.
