Abstract
This present invention generally relates to the issue of signal obstruction in down hole applications. This invention relates to conformal coatings and down hole transmission systems to aid in transmission of wireless signals down hole. The conformal coating includes a substrate material that has an array of rods embedded therein. These embedded rods are made of a Mie Resonance based dielectric material.
