Suppression of EM Fields using Active Control Algorithms
Responsible organisation
2004 (English)In: Radioengineering, ISSN 1210-2512, E-ISSN 1805-9600, Vol. 13, no 3, 22-25 p.Article in journal (Refereed) Published
Abstract [en]

Active methods for attenuating acoustic pressure fields have been successfully used in many applications. In this paper we investigate some of these active control methods in combination with a MIMO antenna system in order to assess their validity and performance when applied to electromagnetic fields. The application that we evaluated in this paper is a model of a mobile phone equipped with one ordinary transmitting antenna and two actuator-antennas which purpose is to reduce the electromagnetic field at a specific area in space (e.g. at the human head). Simulation results show the promise of using the adaptive active control algorithms and MIMO system to attenuate the electromagnetic field power density.
