Power Normalization for Over the Air Augmented Exposure Assessment

This paper concerns the challenges of power normalization for soft excitation equivalent field sources in reflective environments in the context of exposure assessment. At first, the principle of the over-the-air augmented (OTAA) method and the need for adequate power normalization in exposure assessments is explained. By the example of 1D finite difference time domain (FDTD) simulations and equivalent circuit (EC) considerations it is then discussed how the total power radiated by field sources is affected by reflections from its environment, and how this can be considered in power normalization. Finally, two improvement approaches are addressed.
