RESULTS OF THE MEASURING AND SIMULATION
OF THE ELECTROMAGNETIC FIELD
OF MOBILE PHONES IN THE HUMAN HEAD REGION

Abstract. The rapid growth of the mobile phone industry has lead
to increasing exposure to electromagnetic radiation which is emitted by
mobile phones, so there is a logic question of the health risk to users
of mobile phones. For that purpose, much of the research in this field
has involved the applying of many measurements of electric field strength,
magnetic field strength and the SAR (the specific absorption rate) and
their comparison with the values which are formed by appropriate standards.
Because of disability of measuring electric field strength, magnetic field
strength and SAR inside of the involvement of the human body, many programs
have been developed which can calculate the listed dimensions and show
their distribution inside of the human body. For success calculation, it
is necessary to construct an appropriate simulation model, set up appropriate
frequency and area of the electromagnetic field. This paper gives the results
of a simulation involving the head region – the inside and outside of
a human head for three different types of mobile phones as well as the
results of measurements made using instrument outside of the human head.
The program which we used for the simulation was the HFSS 10.

REZULTATI MERENJA I SIMULACIJE ELEKTROMAGNETNOG
POLJA
MOBILNIH TELEFONA U REGIONU LJUDSKE GLAVE
Sve veća upotreba mobilnih telefona dovodi do povećanog izlaganja elektromagnetnom
zračenju koje mobilni telefoni emituju, pa se logično postavlja pitanje
rizika po zdravlje korisnika mobilnih telefona. Za tu svrhu, vrše se mnoga
merenja jačine električnog polja, jačine magnetnog polja i SAR-a (specifična
stopa apsorpcije) i upoređivanje pomenutih veličina sa vrednostima koje
su propisane odgovarajućim standardima. Zbog nemogućnosti merenja jačine
električnog polja, jačine magnetnog polja i SAR-a unutar ljudskog tela,
razvijeni su mnogi programi koji mogu proračunati pomenute veličine i
prikazati njihovu raspodelu unutar ljudskog tela. Za uspešan proračun
neophodno je konstruisati odgovarajući simulacioni model, postaviti odgovarajuću
frekvenciju i delokrug elektromagnetnog polja. Rad daje rezultate simulacije
u regionu glave - unutar i van glave čoveka za tri različita tipa mobilnih
telefona kao i rezultate merenja pomoću mernog instrumenta van glave.
Program koji je korišćen za simulaciju je HFSS 10.
