Abstract

See full text

The disclosed jacket comprises a layer that is discreet with respect to the visible and infrared frequencies, having a specified thickness, with a specified dielectric permittivity and emissivity close to 1 for the infrared frequency bands considered; a resistive layer, with an electrical resistivity and thickness that are determined so that the inverse of their product gives a specified resistance; a layer of dielectric material with a specified thickness and a specified dielectric permittivity; and a conductive layer with electrical conductivity determined so that it is considered as a reflective plane for the radar frequencies considered.
