Bandwidth Limit and Synthesis Approach for Single Resonance Ultrathin Metasurfaces
Ashif A. Fathnan, Andreas E. Olk, David A. Powell
Metasurfaces have emerged as a promising technology for the manipulation of electromagnetic waves within a thin layer. In planar ultrathin metasurfaces, there exist rigorous narrow…
High-efficiency refracting millimeter-wave metasurfaces
Andreas E. Olk, Pierre E. M. Macchi, David A. Powell
Printed circuit metasurfaces have attracted significant attention in the microwave community for their versatile wavefront manipulation capability. Despite their promising potentia…
Accurate metasurface synthesis incorporating near-field coupling effects
Andreas E. Olk, David A. Powell
One of the most promising metasurface architectures for the microwave and terahertz frequency ranges consists of three patterned metallic layers separated by dielectrics. Such meta…
