Within the modified four-sublattice model of RbHSO₄ with taking into account the piezoelectric coupling to the strains εi, ε₄, ε₅, and ε₆, the polarization components, static and dynamic dielectric permittivity of clamped and free crystal are calculated in the mean field approximation. At the proper...
