[NewCandle] Chiral metamaterial for repulsive casimir force.

[Keith Nagel]

Hey Horace, I've been thinking about your comments
regarding real vs virtual photons. Let me try
to rephrase the arguments against a ZPF radiometer
in terms of energy.

In the case of ordinary materials, a pair of plates
with a thin gap will only allow a harmonic range
of virtual photon frequencies inside the gap, with
a full range outside. Because the vacuum energy inside
the gap is smaller than outside, the plates press towards each
other.

A pair of plates composed of the claimed metamaterial
would create _greater_ virtual photon energy inside the gap
than outside, and would act as a concentrator
of ZPF rather than an excluder. The resulting
force would cause the plates to repel. This perhaps is
a problem for thermodynamics, but I do see some
other ref's to repulsive casimir forces so maybe in
practice this is not a problem or the repulsion
is described in some other way?

In a gap of ordinary material and metamaterial,
would the vacuum energy reducing effect of the ordinary
material be canceled by the gain effect from
the metamaterial? By constraining the function
describing the gain in this way, we get zero
net motion of the whole assembly. I don't have
access to the first paper ( here's the abstract )

to know how they describe the repulsive force to
prove out the argument. Does it seem right?

K.

This work appears to be based on the idea the ZPF is comprised of
real photons.  It is my understanding it is comprised of virtual
photons, the mediator of the EM force. In other words the ZPF exerts
brownian type push-pulls in isotropic directions on charged
particles, with a cubic frequency distribution. If the ZPF were
comprised of real photons then a sail clearly *would* be possible
(though a bit weak) by merely absorbing photons on one side and
reflecting on the other, in effect a radiometer in a total vacuum -
one which turns the opposite direction from the normal Crookes
radiometer.

I don't know if you have seen it or not, but I provided a proof that
a net ZPF induced force in a vacuum is not feasible, but a Casimir
motor is feasible, here, p 6 ff:
