The existence of specific bioeffects due to high peak power microwaves and their potential health hazards are among the most debated but least explored problems in microwave biology. The present study attempted to reveal such effects by comparing the

Publikováno v: Bioelectromagnetics. 20:216-223

Intense flashes of light were observed in sodium bicarbonate and hydrogen peroxide solutions when they were exposed to pulsed microwave radiation, and the response was greatly enhanced by a microwave-absorbing, biosynthesized polymer, diazoluminomela

Ultrawide-Band Electromagnetic Pulses Induced Hypotension in Rats

Autor: Satnam P. Mathur, Shin-Tsu Lu, Jonathan C. Lee, Yahya Akyel

Publikováno v: Physiology & Behavior. 65:753-761

The ultrawide-band (UWB) electromagnetic pulses are used as a new modality in radar technology. Biological effects of extremely high peak E-field, fast rise time, ultrashort pulse width, and ultrawide band have not been investigated heretofore due to

Exposure to fast-rise-time ultra-wideband (UWB) electromagnetic pulses has been postulated to result in effects on biological tissue (including the cardiovascular system). In the current study, 10 anesthetized Sprague-Dawley rats were exposed to puls

The study replicated the effect of low-intensity millimeter waves (MMW) on isolated nerve function and characterized its dependence on radiation intensity. MMW exposures lasted for 23 min at 0.02, 0.1, 0.5, or 2.6 mW cm−2 (41.34 GHz) and were accom

Effects of a short-term exposure to millimeter waves (CW, 40-52 GHz, 0.24-3.0 mW/cm2) on the compound action potential (CAP) conduction were studied in an isolated frog sciatic nerve preparation. CAPs were evoked by either a low-rate or a high-rate e
