An assembly comprising a device and an obstacle subjected to an incident electromagnetic wave of wavelength &#x3bb;. The obstacle is formed from an electrically conductive material and has a substantially cylindrical shape of transverse dimensions r with respect to a longitudinal axis (O, ez). The longitudinal axis is substantially perpendicular to a propagation direction of the incident electromagnetic wave. The obstacle further has a maximum transverse dimension d such that the ration &#x3bb;/d is less than 1. The device is placed on all or a part of a surface of the obstacle and comprises a sleeve with a dielectric coating of equivalent relative permittivity EREQ, of height hP along a longitudinal axis of the sleeve, substantially equal to formula A, and a sleeve with an electrically conductive coating placed on the periphery of the dielectric coating.
