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.
