Large-angle beam coverage is a critical requirement in next-generation wireless systems, such as joint communications and sensing, autonomous driving, and unmanned aerial vehicles, which demand robust connectivity across broad spatial domains. Achieving large-angle beam steering, especially beyond ±60°, poses substantial challenges in terms of antenna design, efficiency, and system integration. This talk presents recent advances in enabling large-angle beam coverage, focusing on the development of antennas, phased arrays, and engineered metasurfaces. We will explore how these designs can be optimized to overcome conventional limitations and deliver wide field-of-view performance without compromising gain or introducing significant sidelobes. In addition to showcasing recent results, the talk will discuss current research gaps and potential opportunities that may guide future investigations and developments in this field.

Very Low Frequency (VLF, 3–30 kHz) radio waves propagate within the spherical waveguide formed by the Earth’s surface and the lower boundary of the ionosphere. They possess advantages such as resistance to high-altitude nuclear interference, low atmospheric attenuation, and strong penetration capability, making them the most reliable means of long-distance, cross-medium communication with underwater platforms.

To achieve communication over several thousand kilometers, the radiation power of VLF transmitting systems must reach the level of hundreds of kilowatts or more. Since the wavelength of VLF electromagnetic waves ranges from 10 to 100 km, the transmitting antennas of traditional VLF communication stations are typical high-power electrically small antennas, which face unique engineering challenges.

This report will systematically elaborate on the technical characteristics of representative foreign VLF transmitting antennas, analyze the difficulties and challenges encountered by such electrically small antennas in achieving high-power and high-efficiency radiation, and reflect on their future technological development pathways.

This lecture mainly introduces research progress in feature-assisted antenna optimization design based on machine learning. The antenna optimization process requires repeated large-scale electromagnetic simulations, which result in high computational costs and long design cycles. At the same time, antenna optimization faces the challenge of rapidly searching among multiple competing performance indicators.

Optimization methods based on machine learning surrogate models provide an effective approach to addressing the high computational cost and lengthy design cycle of antenna optimization. In such surrogate-model-based optimization, the introduction of feature parameters to assist multi-objective optimization algorithms can significantly enhance the search capability of the algorithms and improve optimization efficiency.

Transparent and stealth communication devices are among the most sought-after and actively explored goals of scientists and engineers. With their outstanding optical or radio-frequency stealth characteristics, such devices can operate silently in everyday human life while delivering extraordinary performance advantages.

Against the backdrop of next-generation wireless communication technologies, the demand for integrated and densely deployed communication devices is growing rapidly. Optical and radio-frequency stealth can significantly enhance device integration, greatly reduce band interference, and improve system radiation clearance.

However, existing technologies struggle to achieve simultaneous stealth in both optical and radio-frequency spectra for electromagnetic communication devices, and are often accompanied by issues such as poor optical transmittance, low radiation efficiency, and difficulties in flexible or topological transmission.

This report focuses on research into flexible electromagnetic communication technologies with dual stealth in optical and radio-frequency bands, aiming to address these challenges and facilitate the integrated, dense, and imperceptible deployment of communication devices.

Leaky-wave antennas (LWAs) are a special class of antenna structures that combine the characteristics of waveguide transmission and space radiation. Since the first leaky-wave antenna was introduced in the 1940s, LWAs have attracted wide attention due to their advantages of high directivity, narrow beamwidth, simple feeding schemes, and frequency-dependent beam scanning.

With this unique frequency-scanning capability, LWAs demonstrate broad application prospects in various low-cost wireless systems such as imaging, sensing, and wireless power transfer, making them a research focus in both academia and industry.

Against this backdrop, this report will highlight several emerging concepts and design techniques of leaky-wave antennas, aiming to endow antennas with more flexible functionalities and superior electromagnetic performance, thereby providing new ideas and solutions for the development of future wireless systems.
