Professor Dragan Poljak from the Department of Electronics, University of Split, Croatia, gave a special seminar at Ashurst Lodge on “Some Measures of Human Body Transient Response” in which he referred to the potential biological effects of electromagnetic pulses to human health.

Dragan firstly presented a direct time domain calculation of the human body transient response. This mathematical model has been based on the so called human equivalent antenna model – a cylindrical representation of the human body and on the related space-time Hallen integral equation. This integral equation has been efficiently solved via the Galerkin-Bubnov scheme of the boundary element method (GB-BEM).

He presented some measures of the transient response of the human body, in terms of: average value of transient current, root-mean square value of the transient current, instantaneous power dissipated in the body, specific absorption and total energy absorbed in the body. The computation of these parameters is carried out via an efficient BEM scheme.

The lecture finished with a lively discussion related to the particular details regarding the human equivalent antenna model and some specific relationships between the peak values of transient current and the related measures.

Dragan holds an Adjunct Associate Professorship at the Wessex Institute and is in charge of the International Master on Electromagnetic Compatibility organised by the Wessex Institute of technology and the University of Split.
