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