two-component mixture in which there are no distinguishable inclusions of one
component within the other. As such it is probably not a reasonable description of
fluffy particles.
Maxwell Garnett (1904) (the name “Maxwell” was actually a given name to the
son of the physicist William Garnett because of the latter’s admiration of his friend,
James Clerk Maxwell) derived an average dielectric function under the assumption
of small inclusions in vacuo, i.e.
