Effects of Packaging Shape, Polarization, Irradiation Geometry, and Frequency on the Computation of Electric and Magnetic Fields and SAR in Water Containers
Year: 2014
Type: preprint
Abstract: The research works on the biological effects of electromagnetic (EM) radiation have increased globally. The exposure of these EM fields holds possible implications on biological materials. Computer simulation models were developed to assess exposure of square, rectangular, pyramidal, and cylindrical water containers to microwave radiation at 300, 900, and 2,400 MHz. The development of the models included determination of EM field distribution and the resulting specific absorption rate (SAR) in the stored water. These models employed CST STUDIO SUITE 2014 package to solve EM field equations by applying the finite-difference time-domain (FDTD) method. The effect of frequency, packaging shape, and polarization on SAR induced in water was determined. High electric and magnetic fields, total SAR, and maximum point SAR were obtained over the whole azimuth and elevation angles range in the pyramid-shaped container. The order of the effect on total SAR and maximum point SAR is cylindrical < square < rectangular < pyramidal model at 300, 900, and 2,400 MHz for both vertical and horizontal polarizations. It can be concluded that the variation in the packaging shape of the containers, polarization, irradiation geometry, and frequency significantly affect the calculation of electric and magnetic fields and SAR values induced in the stored water.
