摘要
Measurements of the complex dielectric constant, or relative permittivity, spectrum of liquid water are modeled for frequencies up to 1 THz and temperatures up to 60 degrees C by a combination of two components: a Debye function, which characterizes the reorientation of the water molecules under the influence of an electric field, and a distributed-resonance function, which is associated with vibrations of intermolecular hydrogen bonds. This model provides a good representation of cloud measurements below 200 GHz at temperatures as low as -25 degrees C.
