Absorption of Microwaves by Microorganisms

Nature, 1969
RECENTLY S. J. W. and Dodds reported that 136 GHz microwaves interfere with the growth of Escherichia coli cells1. Here we report further investigations of the absorption of 65 to 75 GHz microwaves by cells of E. coli BR as well as isolated protein, RNA and DNA, and its effect on some metabolic processes. Our equipment has been described1,2. Cells were

Periodic microwave absorption in superconductors

Physical Review B, 1994
A model explaining the presence of a periodic train of microwave absorption lines in the magnetic modulated microwave absorption (MMMA) spectra of high- and low-temperature superconductors is proposed. The model assumes the occurrence of regular superconducting current loops, closed by Josephson junctions, in these materials.

Microwave absorption spectroscopy of DNA

Biopolymers, 1993
AbstractBy utilizing a novel approach to microwave spectrometry, we have measured the absolute absorption spectrum of plasmid DNA (pUC8.c2), in buffered aqueous solution, from 5 to 20 GHz. Our technique does not suffer from the same experimental difficulties that plague other methods.

Absorption of microwaves in the microwave oven

The Physics Teacher, 2001
A microwave oven is used to demonstrate that, in comparison to liquid water, both ice and liquid nitrogen are almost completely transparent to microwaves. The difference in transparency is also simply explained.
