Exposure of Insects to Radio-Frequency Electromagnetic Fields from 2 to 120″‰GHz
Scientific Reports volume 8, Article number: 3924 (2018)
Abstract
Insects are continually exposed to Radio-Frequency (RF) electromagnetic fields at different frequencies. The range of frequencies used for wireless telecommunication systems will increase in the near future from below 6″‰GHz (2″‰G, 3″‰G, 4″‰G, and WiFi) to frequencies up to 120″‰GHz (5″‰G). This paper is the first to report the absorbed RF electromagnetic power in four different types of insects as a function of frequency from 2″‰GHz to 120″‰GHz. A set of insect models was obtained using novel Micro-CT (computer tomography) imaging. These models were used for the first time in finite-difference time-domain electromagnetic simulations. All insects showed a dependence of the absorbed power on the frequency. All insects showed a general increase in absorbed RF power at and above 6″‰GHz, in comparison to the absorbed RF power below 6″‰GHz. Our simulations showed that a shift of 10% of the incident power density to frequencies above 6″‰GHz would lead to an increase in absorbed power between 3″”370%.

Conclusions
We investigated the absorbed radio-frequency electromagnetic power in four different real insects as a function of frequency from 2″”120″‰GHz. Micro-CT imaging was used to obtain realistic models of real insects. These models were assigned dielectric parameters obtained from literature and used in finite-difference time-domain simulations. All insects show a dependence of the absorbed power on the frequency with a peak frequency that depends on their size and dielectric properties. The insects show a maximum in absorbed radio frequency power at wavelengths that are comparable to their body size. They show a general increase in absorbed radio-frequency power above 6″‰GHz (until the frequencies where the wavelengths are comparable to their body size), which indicates that if the used power densities do not decrease, but shift (partly) to higher frequencies, the absorption in the studied insects will increase as well. A shift of 10% of the incident power density to frequencies above 6″‰GHz would lead to an increase in absorbed power between 3″”370%. This could lead to changes in insect behaviour, physiology, and morphology over time due to an increase in body temperatures, from dielectric heating. The studied insects that are smaller than 1″‰cm show a peak in absorption at frequencies (above 6″‰GHz), which are currently not often used for telecommunication, but are planned to be used in the next generation of wireless telecommunication systems. At frequencies above the peak frequency (smaller wavelengths) the absorbed power decreases slightly.
