Theoretical exploration of factors affecting dielectric constants of masson pine
A theoretical model to calculate the dielectric constant of
masson pine (Pinus massoniana) in the longitudinal direction
was developed by considering the effect of wood
moisture content, density, ratio of earlywood to latewood,
and the volume fraction of ray cells. The calculated
results were used to explore the relationship between
dielectric constant and moisture content, density, and
other factors. The results indicated that the dielectric
constant of masson pine increased with the moisture
content. From 0% to 30% moisture content, the longitudinal
dielectric constant increased more than 5 times
from 2.3 to 13.3. In the range of density from 0.450 to
0.650 (g cm?3 at 15% moisture content, the longitudinal
dielectric constant increased from 7.7 to 10.0. However,
the longitudinal dielectric constant decreased as the volume
fraction of ray cells increased.
