Phase-Gradient Huygens’ Metasurface Coatings for Dynamic Beamforming in Linear Antennas
نویسندگان
چکیده
The beamforming capabilities of conformal cylindrical Huygens metasurface (HMS) coatings for linear antennas are assessed. It is shown that by engineering the phase-gradient profile HMS, original omnidirectional radiation pattern antenna can be shaped to form multi- or single-beam configurations. A closed-form expression phase-insertion coating required achieve desired derived, and several full-wave numerical examples supporting our claims reported. configuration exploiting a realistic HMS layout also discussed it that, making reconfigurable through use tunable lumped elements, radiated beams dynamically steered in space. This new design methodology could find application smart electromagnetic environment scenarios rerouting signal towards multiple users.

Cavity-excited Huygens' metasurface antennas for near-unity aperture illumination efficiency from arbitrarily large apertures
One of the long-standing problems in antenna engineering is the realization of highly directive beams using low-profile devices. In this paper, we provide a solution to this problem by means of Huygens' metasurfaces (HMSs), based on the equivalence principle. This principle states that a given excitation can be transformed to a desirable aperture field by inducing suitable electric and (equival...
متن کاملLinear dynamic response of nanobeams accounting for higher gradient effects
Linear dynamic response of simply supported nanobeams subjected to a variable axial force is assessed by Galerkin numerical approach. Constitutive behavior is described by three functional forms of elastic energy densities enclosing nonlocal and strain gradient effects and their combination. Linear stationary dynamics of nanobeams is modulated by an axial force which controls the global stiffne...
متن کاملMetasurface Antennas for User Terminal
In this paper we discuss some results for a metasurface antenna radiating a sectorial beam with circular polarization. From numerical simulations we obtained 25 dBi of gain at around 60° off-axis angle from an antenna with 7.5λ radius. Light weight, low profile and low cost (a standard PCB process can be used to realize the metasurface) are interesting characteristics of such devices, making th...

متن کاملA Multilayer Metasurface Cloak Coating for Monopole Antennas
A multilayer metasurface cloak coating is introduced for monopole antennas. It retains the input impedance and radiation parameters of the antenna for its original operational band. At the same time, it also reduces the monopole’s scattering signature and the received power for the operational band of another system located in close proximity. The coating, consisting of two layers of concentric...
