Welcome to the Guan Group!


We are a dynamic research group at School of Information Science and Engineering in Lanzhou University. Our aim is to explore and understand the intelligent electromagnetic manipulation based on soft functional optoelectronic ionic liquids. using computational calculation and experiments, including THz properties of ionic liquids, microwave absorbers based on ionic liquids and absorption mechanism, electromagnetic manipulation of ionic liquids and application of machine learning in the intelligent electromagnetic manipulation based on soft functional optoelectronic ionic liquids.


UG/PG Student Positions Available


I am looking for self-motivated Master's students with a strong theoretical background in physics, math, and machine learning, or with a strong systems background in electromagnetic field using electromagnetic simulation software (COMSOL, CST, et al.), specialized in Communication and Information System or Electronics and Communication Engineering. Please send me your CV, representative publications (if any), detailed transcripts with GPA and ranking, IELTS/TOEFL/CET scores, along with a brief introduction about yourself if you are interested in working with me. Undergraduate students at School of Information Science and Engineering are encouraged to discuss with me about potential research projects. I am also interested in hosting visiting students.

about image

Ionic liquids are salts composed of organic cations and organic/inorganic anions, and are in liquid state at 25°C. Due to its excellent physical and chemical properties, it is widely used in various fields. The tuned structure and properties make it the most promising new type of soft-functional optoelectronic material in the 21st century. Terahertz (Terahertz, THz) wave refers to electromagnetic radiation with a frequency range of 0.1-10 THz (1 THz = 1012 Hz), between infrared and microwave. Terahertz waves have unique characteristics such as low energy, high permeability, fingerprints, and broadband, so they are widely used in broadband communications, satellite communications, astronomy, security inspections, medical imaging and other fields. Therefore, our research group uses experimental methods combined with theoretical calculations to study THz properties of ionic liquids, microwave absorbers based on ionic liquids and absorption mechanism, electromagnetic manipulation of ionic liquids, and application of machine learning in the intelligent electromagnetic manipulation based on soft functional optoelectronic ionic liquids.

Surely it is not knowledge, but learning; not owning but earning; not being there, but getting there; that gives us the greatest pleasure.
