Within the framework of a modified proton ordering model of the KH₂PO₄ family ferroelectric crystals, taking into account a linear over the strain ε₆ contribution into the proton system energy, we obtain an expression for longitudinal dynamic dielectric permittivity of a mechanically clamped crystal...
