Exposure System for Verification of Effects of Electromagnetic Field

The main aim of this work is to design and to simulate an exposure chamber which can simulate mobile phone emission patterns in order to analyze the influence of electromagnetic field on small animals. During our previous research we found the most suitable type of an exposure chamber for this purpose. The basic properties such as electromagnetic field distribution and impedance matching of our designed chamber were optimized and verified by the aid of a 3D electromagnetic field simulator. As a result of our effort a cylinder waveguide chamber with a working frequency 900 MHz has been designed. In the cylindrical structure a circular polarization is excited in order to even the exposure. The chamber is terminated by matched loads on both lateral sides which serve for preventing a possible resonance between sides and the animal.
