Abstract : The report describes experiments on millimeter-wave effects on lambda-prophage induction in lysogenic strains of E. coli, temperature-sensitive mutants of lambda prophage, and Salmonella typhimurium cells possessing Hismutation. No frequency-sensitive irrdation effects have been observed in spite of closely spaced frequencies used in the 42-48 and 65-75 GHz bands. A new method for measuring complex permittivities of biological media, with potential for in-vivo measurements, has been proposed that alleviates the need for samples with submillimeter thicknesses. Initial results appear to be highly promising. A system to allow low-wave-number Raman and Brillouin spectroscopy of biological media has also been set up.
