The beamforming capabilities of conformal cylindrical Huygens metasurface(HMS) coatings for linear antennas are assessed. It is shown that byengineering the phase-gradient profile of the HMS, the original omnidirectionalradiation pattern of the linear antenna can be shaped to form multi- orsingle-beam configurations. A closed-form expression for the phase-insertionprofile of the cylindrical coating required to achieve the desired radiationpattern profile is derived, and several full-wave numerical examples supportingour claims are reported. A configuration exploiting a realistic HMS layout isalso discussed and it is shown that, by making the metasurface reconfigurablethrough the use of tunable lumped elements, the radiated beams can bedynamically steered in space. This new design methodology could findapplication in smart electromagnetic environment scenarios for dynamicallyrerouting the signal towards multiple users.
