A two-wire probe is investigated as a possible sensor for brain edema monitoring. A dual monopole antenna model for a two-wire dielectric probe is presented. Model results for water and saline are found to agree closely with measured data. A model of brain tissue permittivity and loss as a function of tissue water fraction is developed and used in the probe model to predict probe operation.
