Zixiao Zhang
Runner Up
What encouraged you to submit your application to the 2024 Postgraduate Research Publication of the Year?
Being selected as a Rising Star last year was a great encouragement and motivated me to apply again. This year’s paper represents a key milestone in my PhD research, introducing a scalable, multifunctional RF design. I saw this award as an opportunity to share my latest work more broadly and was also encouraged by my supervisor and peers.
What inspired you to choose the subject of your paper?
This work builds on my earlier research on unilateral filtering networks and takes a significant step forward by integrating additional functionalities such as phase shifting and attenuation, which are in high demand. My goal was to broaden the applicability of spatiotemporally modulated resonator arrays to more advanced RF systems. The idea stemmed from my drive to develop scalable, compact, and multifunctional RF front-end solutions tailored for next-generation communication applications.
What’s your paper about and how did you prepare for it? What role did research excellence play in your approach?
The paper presents a new RF co-design methodology that enables the integration of five key functionalities—bandpass filtering, RF isolation, variable phase shifting, variable attenuation, and switching—within a single, compact device using spatiotemporally modulated resonators. The proposed approach is topology-independent and reconfigurable, allowing users to build multifunctional components for different RF applications.
To prepare for this paper, I conducted a comprehensive theoretical analysis to lay a solid scientific foundation for the study. Following this, I led the simulation and measurement of the circuits.
I ensured excellence in the research process by adhering to a rigorous, repeatable methodology and cross-validating theoretical, simulated, and measured results. This attention to detail was critical for establishing confidence in the novelty and practical relevance of the proposed solution.
The selection for Research Publication of the Year is extremely competitive. What is your advice for those aspiring for nomination next year?
My advice would be: start with a strong foundation in theory, validate your work thoroughly, and don’t underestimate the importance of writing—great results deserve great presentation.
What is the single most significant support Tyndall has been able to offer you in achieving your research goals?
Tyndall has provided a truly supportive research environment that was essential to the success of my work. The access to specialised lab equipment and facilities allowed me to fabricate and characterise high-frequency prototypes in-house. The collaboration and flexibility from lab managers, especially when coordinating measurement schedules and access, were incredibly helpful.
