Abstract:

This paper reports the analysis of EM wave propagation in human tissue, with specific reference to

radio-frequency wave propagation. Maxwell’s equation is applied to analyse and model the behaviour of

the EM wave as it transits from the free-space as a source-free region into human tissue. Maxwell’s

equations have never been used in this manner before. The transmitted wave is theoretically followed into

the human skin. Measured electric fields from GSM towers and frequencies used by the four major

wireless service providers in Nigeria, coupled with the modelled equation for the transmitted wave in the

skin are used to simulate the wave propagation in the tissue. MATLAB software, a versatile engineering

tool is used to simulate the propagation model in human tissue. Measurement of the EM wave radiated by

some sources into free-space is carried out. Results obtained from computation using the developed

propagation model in human tissue are compared with standards and existing results. Results show that the

EM wave radiating around our immediate environment and hitting our skin does not travel deep into our

body. The frequencies used by these GSM network providers for 3G and 4G transmission are low and do

not possess enough energy to cause damage to the tissue.
