Huygens'Metasurface Based on Induced Magnetism and Its Application in Millimeter-wave Lens Antenna
Metasurfaces have shown great potential for applications in modern wireless communications and millimeter-wave radar due to their powerful electromagnetic manipulation capabilities.And realizing as many electromagnetic functions as possible on metasurfaces with extremely simple structure is what the engineering community strives for.A systematic study of Huygens'metasurfaces with simplified structure is carried out based on the induced magnetism,and a comprehensive review is presented for their potential applications in millimeter-wave lens antennas.The induced magnetism is able to utilize the double-layer metallic patterns on a single-layer Printed Circuit Board(PCB)substrate to excite the magnetic resonance and hence the Huygens resonance,which breaks through the phase-shifting limitation of the conventional frequency-selective surfaces in terms of electromagnetic wave manipulation.The properties pave the way for efficient transmitted-wave manipulation on the very simple metasurfaces.Potential applications of Huygens'metasurfaces include single-polarized,dual-polarized,dual-band,low-profile,and transmissive/reflective bifunctional metalens antenna designs.Since it can be prepared using a single-layer PCB substrate which make the fabrication much easier and lower cost,the Huygens'metasurfaces based on the induced magnetism have important applications for future antenna engineering.
