Yan-Jyun Liu

[About Me]

My name is Yan-Jyun Liu, and I am currently a second-year master's student in the Department of Electrical Engineering at Yuan Ze University, where I conduct research under the guidance of Professor Cheng-Nan Chiu. I am proficient in operating electromagnetic simulation analysis software (HFSS, FEKO, etc.) and have the ability to operate network analyzers for measurement and verification.

[Educational Background]
• Professional Research and Academic Practice
During my graduate studies, I have consistently maintained a proactive and meticulous approach to deepening my academic research. I have extensively and deeply read top journal articles in the field, which has not only allowed me to grasp the latest technological trends but, more importantly, enabled me to learn systematic problem analysis and solution methods from the experience of experts and scholars.

• Commissioned Projects and Practical Results
I actively participated in industry-academia collaboration projects and successfully completed the Ministry of Economic Affairs Standards, Metrology and Inspection Bureau commissioned project, "Development of Advanced RF and Electromagnetic Compatibility Technology for Heterogeneous Network Elements – Superior Bandpass Shielding Technology," by the end of 2025. This project applied theoretical knowledge to solve practical electromagnetic compatibility (EMC) and radio frequency (RF) problems, successfully developing a high-performance metabandpass shield. This achievement provides an innovative solution for electromagnetic interference suppression of heterogeneous network elements.

• International Exchange and Academic Submission
To promote my research findings on the international stage, I also participated in the writing and submission of a paper for the 2026 Asia-Pacific International Symposium and Exhibition on Electromagnetic Compatibility (APEMC). The paper is currently under review. This submission experience familiarized me with the standards and procedures of international academic conferences and provided an opportunity to exchange ideas with top scholars worldwide.

• Master's Thesis and Technical Discussion
After completing the above project and submission, I did not rest but instead focused on my master's thesis—research on Rasorbers. A Rasorber is an advanced electromagnetic metamaterial. My research goal is to optimize the structure and control parameters to achieve the optimal broadband absorption and scattering performance of the Rasorber, contributing to the development of future stealth technology.

[Career Development]

During my studies, I participated in numerous group activities (sports team, scout corps, drama club), gaining a deep understanding of the importance of teamwork and communication. What I hope to join is a team where I can work with supervisors and colleagues to leverage our strengths, contributing to the company's growth and generating more revenue.
Furthermore, in today's rapidly evolving technological world, it is essential to constantly strive for continuous learning and advancement. While pursuing corporate growth, I must also simultaneously improve my own professional knowledge and skills to meet the challenges of future high-level technologies.

• Yan-Jyun Liu, Cheng-Nan Chiu, Chiu-Kuo Chen, Chih-Hong Lee, “An Evolvable Single-Layer Ultrawideband Bandpass Frequency-Selective Surface” , I have submitted a paper to the 2026 APEMC (Asia-Pacific International Symposium and Exhibition on Electromagnetic Compatibility) international conference, and the paper is currently under review. This submission experience has familiarized me with the standards and procedures of international academic conferences and provided an opportunity to exchange ideas with top scholars from around the world.
• Abstract：

       An ultrawideband bandpass frequency selective surface (FSS) is proposed. The single-layer 2-D metallic pattern adopts an evolvable grid-like form whose geometrical parameters can be progressively modified to extend the passband. A prototype is designed, simulated, and measured, exhibiting low in-band insertion loss and strong out-of-band suppression. Its pass band is from 1.84 to 9.52 GHz, fully covering the S and C bands. The fractional bandwidth (FBW) is up to 135.2%, which is really demonstrating the suitability of the proposed FSS for wideband communication, radar, and electromagnetic shielding applications.
