Main Human Interaction with Electromagnetic Fields: Computational Models in Dosimetry

Human Interaction with Electromagnetic Fields: Computational Models in Dosimetry

,
There has been a continuous controversy whether the
presence of electromagnetic fields pertaining to the
non-ionizing part of the spectrum in the environment
could be associated with health risk. The biological
effects of electromagnetic fields are appreciably de-
pendent on actual intensity and frequency, therefore a
rough classification is often related to low frequency
(LF) and high frequency (HF) exposures. Consequently,
an assessment of distribution of the fields induced in bi-
ological bodies is crucial to study the related biological
effects.
The present book aims to provide necessary infor-
mation regarding computational models in electromag-
netic and thermal dosimetry.
Chapter 1 provides general considerations of human
exposure to electromagnetic fields, while some basics of
computational electromagnetics are given in Chapter 2.
Chapter 3 deals with theoretical and experimental
procedures on incident field dosimetry covering LF and
HF electromagnetic interference (EMI) sources.
Simplified (canonical) models of the human body
are presented in Chapter 4.
The central part of the book is given in Chapters 5
and 6, in which realistic models of the human body at
LF and HF exposures based on Finite Element Method
(FEM) and Boundary Element method (BEM), hybrid
FEM/BEM and Method of Moments (MoM) are given.
Furthermore, biomedical applications of electromag-
netic fields are given in Chapter 7. Therefore, in addition
to unwanted human exposure to LF and HF sources,
of particular interest are also some biomedical applica-
tions of electromagnetic fields.
Finally, some useful mathematical details are avail-
able in Appendices A to F.
Rigorous theoretical background accompanied with
mathematical details of various formulations and re-
lated solution methods being used throughout the book
are presented.
The book includes many illustrative computational
examples arising from realistic exposure scenarios and
a reference list at the end of each chapter.
The intention of the present book is to provide not
only useful description of our own expertise concerning
bioelectromagnetics, but also to give updated informa-
tion on some of the latest advances in this area.
We hope that this book will be useful material for
undergraduate, graduate and postdoc students, as well
as engineers in the industry, to learn about advanced
computational models in electromagnetic and thermal
dosimetry and to tackle some problems arising from re-
alistic exposure scenarios.
We also think that the book could be used for var-
ious university courses involving bioelectromagnetics
and computational dosimetry.
The book requires a general background in electrical
engineering, involving some topics in basic electromag-
netics. Fundamental concepts in bioelectromagnetics as
well as numerical modeling principles are given in this
book. Thus, the book is convenient for students, special-
ists, researchers and engineers.
To sum up, we are glad we have managed to compose
this material stemming from more than two decades
of rather intensive research in bioelectromagnetics. Of
course, there are many rather challenging problems we
would like to tackle in the future, such as stochastic bio-
electromagnetics.
