Manuscript Data for the Ka band phase shifter based on the NFA based small molecule

This communication introduces a Ka-band phase shifter that leverages a blend of the donor polymer PM6 and non-fullerene acceptor (NFA) Y7 organic materials. The design integrates a coplanar waveguide (CPW) with a spin-coated thin film of PM6:Y7 blend, characterized by its dielectric nonlinearity and light sensitivity. An applied electric field between the CPW signal and ground electrodes governs the phase shift mechanism, effectively modulating the permittivity of the blend. Our study reveals a significant differential phase shift of up to 28 degrees at 38 GHz across the 1000 um wide waveguide. Additionally, we explore the dynamic interplay between illumination and temperature on the performance of the phase shifter, providing insights into its operational versatility. The findings underscore the substantial potential of NFA-based phase shifters in millimeter-wave applications and adaptive communication systems, such as active antennas, marking a significant stride in developing organic material-based electronic components for self powered next-generation technologies.

本通讯介绍了利用供体聚合物PM6与非富勒烯受体（NFA）Y7有机材料混合而成的Ka波段相移器。该设计将共面波导（CPW）与PM6:Y7混合物的旋涂薄膜相结合，该薄膜以其介电非线性特性和光敏性为特征。在CPW信号与地电极之间的施加电场控制着相移机制，有效地调节了混合物的介电常数。我们的研究揭示了在38 GHz频率下，宽度为1000微米的波导中，相移器表现出高达28度的显著差分相移。此外，我们还探讨了光照与温度对相移器性能的动态影响，为其实用性提供了洞见。这些发现强调了基于NFA的相移器在毫米波应用和自适应通信系统（如主动天线）中的巨大潜力，标志着在开发自供电下一代技术中基于有机材料的电子组件方面迈出了重要步伐。
