This paper proposes the time reversal as an electromagnetic focusing technique for improving deep biological tissues heating. The analysis occurred by full-wave FDTD simulations considering a body of a 6-year-old boy placed within a reverberant environment. The excitation was a pulse at the central frequency of 433.9 MHz. After the time reversal application, the distribution of the computed electromagnetic field shows excellent results in terms of strong spatial focusing within the human body. Examples are given for the head and limb.

Abstract
This paper proposes the time reversal as an electromagnetic focusing technique for improving deep biological tissues heating. The analysis occurred by full-wave FDTD simulations considering a body of a 6-year-old boy placed within a reverberant environment. The excitation was a pulse at the central frequency of 433.9 MHz. After the time reversal application, the distribution of the computed electromagnetic field shows excellent results in terms of strong spatial focusing within the human body. Examples are given for the head and limb.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
