Maybe it has already been applied to the cellphone technology or elsewhere, or
it is just not feasible because dielectric losses...
Dielectric material, lossy in some extent, sets a velocity factor (VF) for wave
propagation in cables.
This makes the physical lenght of the line shorter than freespace size.
Take a Yagi, and fill the space between elements with a material which its
dielectric constant is less than 1.0 (air's).
Would the element spacing, hence the boom lenght, have to be adjusted by a
shortening factor equal to the VF?
