Arbitrary Orthogonal Polarization Decomposition and Routing With Complex Amplitude Modulation via Wheel‐of‐Fortune‐Inspired Metasurfaces

ABSTRACT Multi‐dimensional (amplitude, phase, and polarization) manipulation of electromagnetic (EM) waves has long been a central goal in optics. However, most reported metasurface designs to date have achieved only one‐ or two‐dimensional manipulation due to losslessness and in‐plane symmetry constraints. To address this challenge, we propose and experimentally demonstrate a receiver‐transmitter‐integrated metasurface consisting of receiver, transmitter, and connector inspired by the prize‐selection mechanism of “Wheel‐of‐Fortune”. It functions as a full polarizer, decomposing an incident wave into two orthogonal components and routing them separately into transmission and reflection channels, while enabling three‐dimensional control of transmitted component. To engineer this, we establish a fundamental theory to tailor in‐plane symmetries of transmitting and receiving patches for polarization‐routing transmission and reflection through both global and local rotations of these resonators. Specifically, the amplitude and phase of the transmitted component are set by parametric tuning of C‐slot resonators of the receiver and transmitter, and stripline lengths of the connector, respectively. We finally realize and experimentally demonstrate two metadevices that achieve polarization‐routing transmissive‐reflective holography and an asymmetric beamformer with unequal power and deflection angle, respectively. This work provides a powerful platform to realize multidimensional control of EM waves, which can inspire numerous future applications for next‐generation devices.
