2018. Т. 18, No 1. С. 163–170 163 Introduction In the modern world of international communication, absolutely everyone uses cell phones. Each cell phone emits the minimum amount of high-frequency electromagnetic energy. Its power flux density does not exceed 100 μW / cm. This radiation has various effects on human health. Thermal effects can lead to organic damage to body cells. According to public opinion polls among mobile phone users, if they are talking on the phone for more than 20 minutes in a row, the earlobes begin to heat up – this is due to the heating of the blood due to the effect of microwave radiation from cell phones. More serious problems begin with pain in the ears, which can develop into tinnitus or a feeling of constant tinnitus, which ultimately can lead to hearing loss and ear tumors. In addition, the excessive use of cellular phones leads to drying out of the skin and tear fluid in the eyes, sleep disturbance, loss of attention, memory loss and even to the development of many cancers [1]. The degree of absorption by a human body of the radiation of a cellular phone may be depend on the characteristics of the cellular network, the characteristics of the smartphone and its antenna, the position of the antenna, and also the energy of the radiation from the handset [2]. The dielectric properties of the human body also affect the values of the specific absorption rate (SAR), SAR values display the radiated power from mobile smartphone absorbed by human body over a selected volume of 1g or 10 g of body tissues, and it's measured in watt per kilogram (W/kg) [3]. Individual tissues of the human body with an increased water content in them also have higher SAR values. The increased water content in the tissues of the human body means that the tissues of the body have increased conductivity, which means they are more vulnerable, since they are able to absorb electromagnetic waves well. The values of the conductivity and permittivity depend on the frequency of irradiation [4]. Conductivity and dielectric permeability of tissues are constant values if the frequency of irradiation of tissues remains constant. For this reason, a change in the value of the operating frequency ultimately changed the conductivity and dielectric permeability of the tissues. The purpose of the experiment was to calculate and display the electrical field and magnetic field caused by the electromagnetic radiation of the mobile phone, affecting the human head and various components of the mobile phone (plastic casing, metal base of the antenna and metal washer) in linear units and in dB, also three-dimensional (3D) far-field radiation pattern using the EM.CUBE program.
