Investigation of elementary excitations of the generalized Kitaev model plays an important role for understanding the dynamic properties of its solid-state realization. In the present study, we consider linear and non-linear response of the extended Kitaev model induced by an external magnetic field. Linear and non-linear response susceptibilities will be calculated within the Majorana mean-field approach. We discuss how the obtained results can be used for the interpretation of the experimental study of Kitaev-like compounds.
