Calculates the complex dielectric constant of water for a given frequency and temperature using the
model derived by Thomas Meissner and Frank Wentz in "The Complex Dielectric Constant of Pure and
Sea Water from Microwave Satellite Observations". Their paper can be found here
For pure water the model is valid for frequencies up to 500 GHz from a temperature of -20 °C (note that this is super cooled water NOT ice) to +40 °C. For sea water, the model is valid from -2 °C to +29 °C for frequencies up to 100 GHz.
