Radiofrequency/Microwave Cell Absorption and Action Spectroscopy
Abstract
Dielectric properties (viz real and imaginary components of the complex dielectric constant, and the absorption coefficient) were determined for mammalian cells and viruses over the frequency range 50- to 26,400 MHz. Dielectric properties were determined by using an open probe technique which measured the complex reflection coefficient using a Hewlett Packard 8510 network analyzer and associated data processing system. Independent variables investigated included: temperature, cell cycle, metabolic inhibitors, anesthetic agents, ionophores, and fixatives. Under certain conditions, these variables affected the dielectric properties of cells or viruses. No firm evidence of resonant-like absorption of radiofrequency radiation in cell or viral macromolecules, such as DNA, has been obtained.
