Modeling the very broad band dielectric properties of water

Developing a mathematical model for the dielectric properties of water over a wide range of frequencies helps design, develop, model and optimize processes involving the interaction of electromagnetic waves with water containing materials. Based on large data sets (1744 published dielectric measurements) from literature and significant extensions to mathematical models, which have also been presented in literature, a comprehensive mathematical model for the most important dipolar responses and molecular resonances of water, from radio wave to the ultraviolet frequencies has been developed. This model provides a good approximation to published dielectric properties of pure water. Where possible, it also accounts for the influence of salinity and temperature.
