In this paper 1-bit dual-polarized ultra-thin lens antennas are presented based on Huygens’ principle. The unit cell provides two-state transmission phase compensation for waves. By tuning state 0 away from resonance and 1 near resonance, the 180° difference between two states is achieved. frequency range of 27.5–28.5 GHz, ± 20°, amplitude greater than −2 dB. Using proposed cell, three ultrathi...

Control over surface plasmons (SPs) is essential in a variety of cutting-edge applications, such as highly integrated photonic signal processing systems, deep-subwavelength lasing, high-resolution imaging, and ultrasensitive biomedical detection. Recently, asymmetric excitation of SPs has attracted enormous interest. In free space, the analog of electromagnetically induced transparency (EIT) in...

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...

Huygens' metasurfaces (HMSs) have demonstrated the ability to tailor electromagnetic wavefronts with passive low-profile structures. The fundamental constraint enabling and ideally lossless solutions is conservation of normal real power locally along metasurface. In this letter, we examine use auxiliary surface waves design HMSs for wave transformations different incident output density profile...
