Show affiliationsCharged particle colloids typically consist of particles with negative surface charge suspended in an aqueous electrolyte solution, and have been shown to display effective dielectric properties at radio and microwave frequencies which can potentially be tailored for a range of applications. This research describes a model for predicting such properties. A model previously used to account for the dielectric performance at low frequencies is extended to include higher-order terms in angular frequency, ω. The extended model encompasses the high and low frequency relaxation contributions for the dielectric properties of charged particle colloids. The parameters used to tailor these properties are identified.
