Genetic algorithm based reduction of electromagnetic field pollution

Paper describes a method for finding transmitter parameters (location, power and horizontal direction) for optimal electromagnetic radiation distribution in the observed area. Constraints are protected areas inside the observed area where strength of electric field is limited because of a permanent people presence. In the observed area one wishes to obtain the strength of electric field which is higher than the lower limit value to cover the area with enough reception signal power. On the other hand electric field inside protected areas has to be lower than the prescribed upper limit determined by a health hazard. These two conditions are contradictory. In this investigation a genetic algorithm is used to find transmitter parameters (location, power and horizontal direction) constrained by above mentioned conditions. Investigation is limited to a rectangular planar observing area with one transmitter and with different formation and size of protected areas. The procedure has been repeated for 15 times and the results are analyzed statistically. Based on these results it can be concluded that the procedure is applicable and it is justified to continue investigations for more complex and more realistic situations, e.g. more than one transmitter with directed radiations and for 3D spaces.
