Model		Modeling and theoretical calculations of RF energy absorption in biological systems and the possibility of athermal effects
Details		Theoretical calculations of RF energy absorption into biological systems and hypothetical thermal vs. non-thermal effects. The author uses myoglobin protein and the DNA double helix in water as models, and works through vibrational and opposing displacements modes of energy absorption. According to the author, calculations indicate that "absorption below several hundred GHz would not be resonantly absorbed into an intramolecular mode" for either molecule. Any absorption would primarily involve thermalization throughout the bulk material, rather than into a single molecule. He concludes that athermal effects are unlikely to occur. Other efforts addressed whether resonant absorption can occur in macromolecules at radiofrequencies. That is, can RF energy persist long enough in a macromolecule to change its function or structure before being converted to heat?
