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

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.
