Going further, it isn't even necessary to drive temperatures to the
basement for improved conduction. Carbon nanotubes are exemplars of
high conductivity (several orders of magnitude better than what we
consider good metals) at room temperature where a carbon macrotube
would be called a resistor. Conductivity and superconductivity
research has long ago left the realm of temperature and has entered
the realm of crystal alignment.

However, even this academic. Carbon Nanotube construction at a scale
to compete with standard copper wire is off by a scale of a million to
billions (of dollars, much less practicability).

This may have changed also, I'm no expert in superconductors (though I
do play one on TV) Don't the high temperature superconductors have
issues with current capacity, and does this translate into problems with
impedance?

Hi Mike,

High temperature is a relative thing (being it is measured in the 10s
of Kelvins for high temperature superconductivity).

However, Impedance? In the convetional application here in this
forum, it is a remote consideration for research. Afterall, nothing
has changed about the usual characterisitics of conduction,
inductance, or capacitance except for conduction's magnitude/density.

Aside from the conventional discussion here, researchers do tons of
work in the realm of superconductivity that employs radiation. That
body of research is called Plasmonics and Excitonics. Phononics
doesn't strictly apply because it is, by definition, high temperature.

Most of the research into subresonant structures is done in the
nanoscale. What is discussed here as possibilities in that same
regard is sheer nonsense. However, there have been glimmers of
nanoscale research reaching out into the macro dimension.

I've posted such items from Boeing's skunk works on negative
refractive index material research. It is something that could be
modeled in NEC - but only at a vastly expansive scale with hours of
computer time to run.

I am going to broach a taboo and see if an attachment of a split-ring
resonator would be supported.
