Abstract
Potassium dihydrogen phosphate, KH2PO4 (KDP) crystal is an order–disorder type ferroelectric crystal. Earlier model Hamiltonian used by Ganguli et al. is modified by adding other terms to investigate transverse limiting frequency, permittivity, and loss factor in potassium dihydrogen phosphate (KDP) crystal. Green function formalism is used for derivation of formulae. Calculated results agree with experimental data reported by Kaminow and Harding for potassium dihydrogen phosphate KH2PO4 crystal. New terms play important role in explaining quantitatively the transverse limiting frequency, electrical permittivity, and loss factor in potassium dihydrogen phosphate (KDP) crystal.
期刊介绍：
The aims of this peer-reviewed online journal are to distribute and archive all relevant material required to document, assess, validate and reconstruct in detail the body of knowledge in the physical and related sciences.
The scope of EPJ Plus encompasses a broad landscape of fields and disciplines in the physical and related sciences - such as covered by the topical EPJ journals and with the explicit addition of geophysics, astrophysics, general relativity and cosmology, mathematical and quantum physics, classical and fluid mechanics, accelerator and medical physics, as well as physics techniques applied to any other topics, including energy, environment and cultural heritage.
