mobile phone

A smartphone is not only a means of communication, but also a gadget that helps a modern person better understand the effectiveness and optimize some of his own needs. Today, it plays the role of not only a full connection, but also provides constant access to various sources of information, searches for informational opportunities and promotes the popularization of his own content and himself. That is why these gadgets have also rapidly taken an important place in the work of journalists.

RF equipment compliance tests employ electromagnetic field calculation in a head phantom to derive Specific Absorption Rate values. We have hypo­thesized that a biological tissue in certain conditions could act like a dielectric resonator hence affecting the field estimation. To study the resonance effects in a human head, we have formulated an eigenfrequency problem for a structurally realistic 2D human head phantom and solved it by the finite element method. The results have revealed 124 underdamped eigen­frequencies within a 0,2–2 GHz frequency band.
