四元数-MUSIC用于具有大规模偏振阵列的近场严格非圆形光源

近场光镊是近场光学领域中的新型技术，因其可对纳米尺度微粒直接进行捕获和操纵而受到广泛关注。简述了该技术的原理，详细介绍了近场光镊技术的研究进展及其在众多学科领域中的潜在应用。

提出并研究了一种用于超高频（UHF）射频识别（RFID）读取器系统的新型天线。 天线在830-950 MHz的整个UHF RFID频带上具有很强的磁场分布，并且在UHF RFID系统中应用时在检测标签方面具有良好的性能，在各个方向上的增益都低于-10 dBi。 描述了天线配置并解释了工作原理。 为了研究每个参数对天线性能的影响，进行了全面的参数研究，并对结果进行了详细介绍和讨论。 为了证明这一概念，开发并制造了原型。 测量结果表明，该天线可以实现较宽的带宽和低增益，并在天线的近场区域产生相对集中的场分布的强磁场。 因此，这项工作对于UHF近场RFID阅读器应用来说是非常有前途的。

This paper reviews the progress on nano-aperture vertical-cavity surface-emitting lasers (VCSELs). The design, fabrication, and polarization control of nano-aperture VCSELs are reviewed. With the nano-aperture evolving from conventional circular and square aperture to unique C-shaped, H-shaped, I-shaped, and bowtie-shaped aperture, both the near-field intensity and near-field beam confinement from nano-aperture VCSELs are significantly improved. As a high-intensity compact light source with sub-

We have seen a lot of unique features off vertical cavity surface emitting lasers (VCSELs), such as low power consumption, wafer-level testing, small packaging capability, and so on. The market of VCSELs has been growing up rapidly in recent years and they are now the key devices in local area networks using multi-mode optical fibers. In addition, new functions on VCSELs have been demonstrated. In this paper, the recent advances of VCSEL photonics will be reviewed, which include the wavelength e
