Design of K-Band Metasurface Beam Splitter

We present the design and analysis of a Huygens’ metasurfaces for beam-splitting applications in the K-band. The metasurface consists of three dielectric substrates with four etched metallic layers and is designed to operate at the center frequency of 25 GHz. By independently manipulating electric and magnetic resonances through variation in the etched metallic geometries, the device efficiently splits the incident beams in two different refraction angles. Here, we provide a preliminary analysis and numerical simulations of the device, emphasizing its relevance in creating smart wireless environments in the millimeter-wave ranges.
