Abstract
Methods are described for measuring the complex permittivity of aqueous biological solutions at frequencies from a few tens of MHz to several GHz. Values of the dielectric constant and loss of aqueous solutions of triglycine are presented and interpreted in terms of the structure of the triglycine molecule. The peak in dielectric loss due to the triglycine is shown to occur at around 900 MHz at 37°C.Keywords
