Re: LC for SAR

[Kevin Thomas <kjt@cray.com>]

Raed,

I'm unaware of anyone using LC to calculate SAR.
I can describe the technique that I'd suggest to
perform the calculation.

LC provides a "Power Density" probe which calculates the
power density at a point in space (as a function of time).
Individual field vector components or the magnitude can be
selected.

A power density magnitude point probe can be placed in
the dielectric region and the simulation run.  Given this data,
SAR can be calculated for a small (cube-shaped) region around
the probe.

LC has no built-in capability to compute SAR from probe data,
so the post-processing needs to be performed by another tool
(e.g., matlab).

A similar calculation could be performed using a line probe
to get SAR as a function of space, or a plane probe, to get
a visualization of SAR on a plane through the model.  The
data formats get more difficult to manage with these more
complex probe types.
