Time Reversal in Reverberating Structures for Deep Focusing in Human Bodies

The following article focuses on Time Reversal as a focusing technique of electromagnetic fields in biological systems. The analysis took place through numerical simulations performed by Finite Difference Time Domain applied to a numerical human model. The model of interest was the upper chest and head placed within a reverberation chamber. Two simulations have been performed considering difference size of the chamber. The results showed better focus for the larger reverberation chamber where, less field dispersion and greater focused field values have been achieved. This indicates a perfect compatibility of the Time reversal in medical field for biological heating therapies.
