Speech Title: Recent research progress on compact, broadband, high-efficiency parasitic arrays
Abstract: With the miniaturization and integration trends in systems such as terminal devices, base stations, vehicle platforms, and satellite communications, high-gain array antennas with beamforming and polarization customization capabilities are becoming increasingly widely used, while facing ever-stricter performance requirements and challenges. To achieve high gain and specific beam directions, traditional array antennas typically employ parallel/series-fed networks to apply specific excitation amplitudes and phases to each radiating element. However, constrained by their additional feed networks, array antennas often face issues such as increased size, higher insertion loss, narrowed bandwidth, and elevated costs. In modern wireless communication platforms and terminal products with increasingly limited clearance and growing demand for higher gain, there is an urgent need to develop compact, high-efficiency, and broadband high-gain arrays. To address these challenges, this talk focuses on compact, broadband, and high-efficiency arrays based on the near-field coupling mechanism. The talk emphasizes how to achieve efficient control of excitation amplitude, phase, and polarization under the parasitic coupling array configuration.

Speech Title: Theory and Practice of Near-Field Millimeter-Wave Imaging for Human Security Screening
Abstract: Millimeter-wave imaging is a key technology for next-generation security screening, playing an important role in public safety. This talk presents a systematic overview of the theory and practice of near-field millimeter-wave imaging for human security inspection. We first introduce the fundamental imaging mechanisms and representative reconstruction methods in active systems. To address challenges in system cost and acquisition efficiency, we then discuss imaging frameworks based on sparse sampling and array design. Furthermore, hybrid reconstruction approaches that integrate physics-consistent models with data-driven methods are highlighted to improve imaging quality and efficiency. Finally, we explore automatic target detection and recognition techniques, with particular emphasis on robust identification of unknown objects. This talk aims to bridge theory and practice, providing insights for developing efficient, accurate, and intelligent millimeter-wave security imaging systems.
