1.2 Applications of Electromagnetics (EM)

Biomedical ResearchesTo illustrate the electromagneticcomputer simulation to the design ofimplantable devices, a simple pacemakerexample is considered. The exampledevice is about 3.5 x 2 x 2 cm with 2.5cm bent wire antenna. It is designed tosimulate a pacemaker and uses the heartelectrode as the antenna.

1.2 Applications of Electromagnetics (EM)

Biomedical ResearchesAn important topic of discussion today is the impact of radio frequencyelectromagnetic fields on human tissue. People are interested in

- the Specific Absorption Rate (SAR) in the entire head, - the 1 and 10 gram averages of the SAR values including the peak value locations, - the whole-body average SAR throughout the head, - conduction currents on the outer surfaces of the head, - and various antenna characteristics including input impedance and efficiency.
