Toroidal multipole is a special current distribution that has many different characteristics from electric multipole and magnetic multipole distributions. Because of its special properties, the toroidal dipole is a research hotspot in the field of metamaterials and nanophotonics. However, the low scattering of the toroidal dipole moment makes its excitation a challenging task. At present, there are relatively few studies on its specific engineering applications. In this paper, by slotting in the rectangular cavity, the excitation of an equivalent toroidal dipole is successfully achieved over a wide frequency range of 53–58 GHz. Results indicate that under the action of the toroidal dipole, the TE10 mode electromagnetic waves transmitted in the rectangular waveguide are converted into vector beams and are radiated outwards. Further adjusting the spatial distribution of the magnetic dipoles in the toroidal dipoles yields results that indicate that the resonance mode in the slot is still dominated by the magnetic toroidal dipole moment, and the electromagnetic waves radiating outward are vortex beams carrying vector polarization. The scattered energy of each dipole moment inside the antenna is calculated. This calculation verifies that the mass of the vector beam and vector vortex beam is closely related to the toroidal dipole supported by this antenna. The proposed structure can be applied to explorations in vortex filtering, in photon entanglement, and in the photonic spin Hall effect.

为了建立川芎指纹图谱，考察不同剂量⁶⁰Co-γ辐照对川芎8种有效成分的影响，以川芎为材料，采用SHIMADZU Shim-pack GIST C18色谱柱（250 mm×4.6 mm，5 μm）对8种有效成分的标准品和对照品储备液进行分析。设定不同剂量（3 kGy、6 kGy、10 kGy、15 kGy）⁶⁰Co-γ辐照处理川芎，处理后样品通过液相色谱法得到指纹图谱。采用《中药色谱指纹图谱相似度评价系统（2004A版）》对相似度进行评价。结果表明：川芎各成分相似度均大于0.988；在低于10 kGy的射线辐照处理后，川芎的8种有效成分含量无明显差异。结果表明该方法稳定可靠。该研究为辐照技术在川芎品质保障及川芎药材辐照标准的制定提供理论依据和支撑。

设计了一种金属/介质/金属复合光栅与梯度超表面相结合的多功能器件。通过复合光栅的非对称结构实现光的非对称传输，当调制后的波矢量与表面等离极化激元的波矢量相匹配时，金属光栅激发的表面等离极化激元产生单波段光传输；通过梯度超表面实现光的异常反射。当x偏振态光波入射时，不同入射方向可在不同波段激发表面等离极化激元，由于上下光栅的不同周期和非对称的介质环境，光栅可分别在1 128 nm和1 550 nm处实现高透射率；另外在反向入射方向，该器件在1 300~1 400 nm整个波段表现为零吸收，反射率大于90%，可作为反射器。当y偏振态光波入射时，在反向入射方向器件通过相位梯度超表面实现异常反射。该结构可为各种偏振相关的多功能器件和集成光学元件提供参考。
