Purpose: This paper reports a study of electromagnetic field (EMF) exposure of several adult insects: a ladybug, a honey bee worker, a wasp, and a mantis at frequencies ranging from 2.5 to 100 GHz. The purpose was to estimate the specific absorption rate (SAR) in insect tissues, including the brain, in order to predict the possible biological effects caused by EMF energy absorption.

In response to physical and psychological stressors, neurobiological processes are activated to maintain homeostasis. Stress alters the activity of the hypothalamic-pituitary-adrenal (HPA) axis. The mechanism for this effect is not yet clear.

Elevated glucocorticoid levels over a long time harm neurocognitive and neurobiological development and cause deleterious effects. The effects of glucocorticoids depend not only on the concentration and duration of action, but also on the period of life when the effect occurs and gender.

The human head and hand being in the near-field zone of a mobile phone antenna can drastically influence the antenna matching with free space. The goal of the presented research is to study this phenomenon on an inhomogeneous human model for different relative positions and distances of hand and fingers when using a mobile phone. The only safety criteria commonly used to estimate RF exposure impact on humans is the specific absorption rate (SAR).
