  In this paper we consider confinement and screening of the electric field. We
study the behavior of a static electric field coupled to a dielectric function
with the intent of obtaining an electrical confinement similar to what happens
with the field of gluons that bind quarks in hadronic matter. For this we use
the phenomenon of `anti-screening' in a medium with exotic dielectric. We show
that tachyon matter behaves like an exotic way whose associated dielectric
function modifies the Maxwell's equations and affects the fields which results
in confining and Coulombian-like potentials in three spatial dimensions. We
note that the confining regime coincides with the tachyon condensation, which
resembles the effect of confinement due to condensation of magnetic monopoles.
The Coulombian-like regime is developed at large distance which is associated
with {a screening phase
