In the paper, a review of the state of the art on numerical models of the electromagnetic field in biological entities is proposed. In particular, the field produced by cells and the one in which cells and biological tissues are exposed to, is considered; low frequency problems are investigated. Issues and drawbacks of field models in bioelectromagnetics with respect to field models for industrial applications are discussed. Streszczenie. W artykule dokonano przeglądu stanu wiedzy na temat numerycznych modeli pola elektromagnetycznego w biologicznych komórkach. W szczególności, rozważane jest pole wytwarzane przez komórki i to, na które narażone są komórki i tkanki biologiczne; badane są problemy niskiej częstotliwości.. W artykule omówiono problemy i wady spotykane w adaptacji modeli polowych w bioelektromagnetyzmie w odniesieniu do modeli polowych w zastosowaniach przemysłowych. (Modele polowe w niskoczęstotliwościowych problemach bioelektromagnetyzmu). Keywords: numerical field models, low frequency, bioelectromagnetics. Słowa kluczowe: polowe modele numeryczne, niska częstotliwość, bioelektromagnetyzm Introduction In the last decades the investigation of electric, magnetic and electromagnetic fields related to biological systems has become a more and more mature research field. At the beginning, for evaluating electromagnetic quantities, only analytical or experimental models were performed. At first, numerical models were applied in biomechanics in the early Seventies like e.g. [1] and then, as it happened in industrial electromagnetics, they were subsequently applied to bioelectromagnetics in the late Seventies like e.g. [2]. For the sake of an example, in Fig. 1 the number of papers published in the last decades which used finite element or finite difference time domain models in low frequency (Fig. 1) and high frequency (Fig. 2), respectively, are reported [3]. 1970 1980 1990 2000 2010 2020 0 50 100 150 200 Year Num[...]
