Title: Xintu Zeng and Intelligent Reflecting Surface Array Control

Introduction

Xintu Zeng is an inventor associated with South China University of Technology in Guangzhou, China. His work includes a patent for controlling intelligent reflecting surface arrays, a technology designed to support precise management of communication channels.

Latest Patents

Zeng is credited with 1 patent, titled “Device and Method for Controlling Intelligent Reflecting Surface Array.” The invention describes a control voltage module, a voltage amplification module, and a varactor module connected in sequence. The varactor module is embedded in a subunit of the array, allowing each subunit to be controlled independently and continuously.

The control voltage module generates a precise, low-amplitude analog signal. The voltage amplification module raises the signal’s amplitude before sending it to the varactor module, which adjusts its output capacitance. According to the patent description, this approach enables high-precision communication channel management without a digital-to-analog converter chip, potentially reducing manufacturing costs.

Career Highlights

Zeng’s patent highlights an approach to array control that combines analog voltage generation and amplification with varactor-based adjustment. The design focuses on precise, independent control of individual array subunits while avoiding the need for a digital-to-analog converter chip.

Collaborations

The patent lists Xiuyin Zhang and Huiping Yang among Zeng’s collaborators. The work is associated with South China University of Technology.

Conclusion

Xintu Zeng’s patented device and method offer a cost-conscious approach to precise, continuous control of intelligent reflecting surface array subunits for communication channel management.
