本文基于工程教育专业认证标准对培养学生解决复杂工程问题能力的要求,分析了当前自动化测试技术类课程教学过程中存在的问题,提出了以“专业典型复杂工程案例”为中心开展项目化、流水线式教学的自动化测试技术课程群建设方案。课程群建设以校企合作教育联盟为依托,构建课程知识体系,明确课程群的专业核心能力培养目标。然后,将企业的实际项目进行提炼,形成融入行业共性技术的适用于教学的典型复杂工程案例。最后,依据支撑典型复杂工程案例的能力要素,将案例按功能模块进行项目分解,围绕非标自动化测试设备开发全周期开展项目化、流水线式教学与实践。教学实践表明,基于项目驱动的自动化测试技术课程群教学模式可有效改善教学质量,提高了学生解决专业复杂工程问题的能力。 相似文献

This paper presents a review of recent investigational studies on exciting Surface Plasmon Polaritons (SPPs) in MicroWave (MW) and TeraHertZ (THz) regimes by using subwavelength corrugated patterns on conductive or metal surfaces. This article also describes SPP Microstrip (MS) structures at microwave and terahertz frequencies, and compares their significance with that of conventional MS Transmission Lines (TL), in order to tackle the key challenges of high gain, bandwidth size, compactness, TL losses, and signal integrity in high-end electronic devices. Because they have subwavelength properties, surface plasmon polaritons are gaining attention for their improved performance and ability for miniaturization in high-speed dense circuits. They possess comparably minuscule wavelength compared to incident light (photons). Consequently, they can demonstrate stronger spatial confinement and higher local field intensity at optical frequencies. In addition to engineering spoof SPP waveguides, which are created by engraving grooves and slits on metal surfaces to allow operation on at low frequencies (microwave and terahertz), semiconductors with smaller permittivity values and thus lower free charge carrier concentration have been demonstrated as a potential candidate in plasmonic devices. If necessary, further tuning of semiconductor-based SPP structures is aided by controlling the charge carrier concentration through doping, or by external stimuli such as optical illumination or thermal excitation of charge carriers from valence to conduction bands. This article conclusively covers previously elucidated perspectives on manipulating SSPPs in the MW and THz ranges, and emphasizes how these could steer next-generation plasmonic devices. 相似文献
