Computational research on wireless body-area networks (WBAN)
Finnish-Japanese co-project
Using FDTD method and anatomically realistic human body models in the EM-field simulations
In-house codes
Goal: Obtain data and knowledge on RF-field propagation on
and inside human body.
A key figure is the path loss between the
transmitting and receiving antennas.
The project supports the development of future WBAN applications in health care, for instance.
WBAN illustrations:
A
schematic of a wireless body-area network
Ex
amplitude in dB scale for a test simulation.The model is looking in
the +x direction. x-directed current source Jx is at the navel
(f=2450 MHz).One can see that the Ex level of -110 dB reaches the
whole front side of the body
Computational research of human exposure to electromagnetic fields:
SAR studies at radio/microwave frequencies
Body models irradiated with plane waves or with waves from base-station antennas
Modeling: using FDTD method and anatomically realistic human body models
Application of CSC's high-performance computation resources when necessary
SAR=Specific Absorption Rate, FDTD=Finite-Difference Time-Domain
Variation studies related to exposure assessment
How does human body type, size and posture affect SAR?
How do exposure conditions (field polarization, incoming angle, frequency) affect SAR?
Variation results -> "uncertainty estimates of SAR"
for specific exposure scenarios,
