SImulations show 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%. 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 will to used by 5G. (Open access)
