minimal reflection factors of 100% and 60%, respectively. This report
includes higher reflection factors in line with published studies by Hondou
et al, 2006, Hondou, 2002 and Vermeeren et al, 2010. Reflection factors are
modeled at 1000% and 2000% as well as at 60% and 100%, based on
published scientific evidence for highly reflective environments. Hondou
(2002) establishes that power density can be higher than conventional
formulas predict using standard 60% and 100% reflection factors.
"We show that this level can reach the reference level (ICNIRP
Guideline) in daily life. This is caused by the fundamental properties
of electromagnetic field, namely, reflection and additivity. The level
of exposure is found to be much higher than estimated by
conventional framework of analysis that assumes that the level rapidly
decreases with the inverse square distance between the source and the
affected person."
"Since the increase of electromagnetic field by reflective boundaries
and the additivity of sources has not been recognized yet, further
detailed studies on various situations and the development of
appropriate regulations are required."
Hondou et al (2006) establishes that power densities 1000 times to 2000
times higher than the power density predictions from computer modeling
(that does not account properly for reflections) can be found in daily living
situations. Power density may not fall off with distance as predicted by
formulas using limited reflection factors. The RF hot spots created by
reflection can significantly increase RF exposures to the public, even above
current public safety limits.
"We confirm the significance of microwave reflection reported in our
previous Letter by experimental and numerical studies. Furthermore,
we show that 'hot spots' often emerge in reflective areas, where the
local exposure level is much higher than average."
