Equation For Linear Materials
In homogeneous, isotropic, nondispersive, linear materials, there is a simple relationship between E and D:
where ε is the permittivity of the material. For the case of vacuum (aka free space), ε = ε0. Under these circumstances, Gauss's law modifies to
for the integral form, and
for the differential form.

Famous quotes containing the words equation and/or materials:
“A nation fights well in proportion to the amount of men and materials it has. And the other equation is that the individual soldier in that army is a more effective soldier the poorer his standard of living has been in the past.”
—Norman Mailer (b. 1923)
“In daily life what distinguishes the master is the using those materials he has, instead of looking about for what are more renowned, or what others have used well.”
—Ralph Waldo Emerson (18031882)
