3D‐Printed Aerogel Metamaterials with Multiple Heterogeneous Interfaces Enables Integrated Control of Microwave Field, Acoustic Field, and Thermal Field

Advanced Science, EarlyView.
The Direct‐Ink‐Writing (DIW) 3D‐printed aramid nanofibers (ANF)/carbon nanotubes (CNT)/liquid metal (LM) aerogel metamaterial demonstrates an effective and lightweight strategy to achieve polarization insensitive & ultra‐wideband microwave absorption from 2.65‐18 GHz, broadband noise reduction effect in the 2800‐6400 Hz and thermal suppression ...

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

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.

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 Radiation Absorption

Health Physics, 1991
The literature contains much evidence that absorption of microwave energy will lead to behavioral changes in man and laboratory animals. The changes include simple perturbations or outright stoppage of ongoing behavior. On one extreme, intense microwave absorption can result in seizures followed by death.
