Three-dimensional EM modelling of human head at
1700MHz and 900MHz. Three-dimensional EM modelling of fields in the human head at 1700MHz. A very topical issue! The radiating antenna is on the left. Here you see a slice through the middle of the head. Notice the multiple resonance’s to the right of the centre of the head. This was the first publication in the world to draw attention to possible mobile phone and body tissue interactions. The work was performed using our own TLM code and published by a member of Radiowave. Picture Copyright RadiowAve Ltd. |
