Dual-frequency dual orthogonal polarization wave multiplexing using decoupled pixels based on Holographic technique.

The holographic technique is a promising way to manipulate light distribution and wave-front in the optical regime. In recent years, many researchers have extended this concept to microwave regime to manipulate phase, amplitude, and polarization of waves in a convenient way revealing diverse intriguing applications. Unlike the previous studies with optimization-based schemes, in this paper, we propose a simple route to design dual frequency dual-polarization holographic metasurfaces with negligible interference between the operating (lower and upper) frequencies.
