The equalization between the electromagnetic and the hadronic signals is the condition for obtaining the linear response of a calorimeter to hadronic showers and an energy resolution that improves as the incident energy increases. In a calorimeter with silicon readout, the use of a combination of low-Z and high-Z materials as absorbers allows the transformation of the electron energy distribution of the incidence showers in two media with different critical energies. As a result, the response of the calorimeter to incoming showers is modified to achieve the compensation condition (e/h = 1).
