Short biography

My progress started when I entered NODET High School (National Organization for Development of Exceptional Talents) after passing entrance exam. NODET High School, with high qualified and intensive syllabus, are specially designed for the most talented students. I finished my schooling and then enrolled in the Electrical Engineering Program at one of the best technical universities in Iran. I had a good performance in my undergraduate studies. I maintained a good ranking in communication branch of the Electrical Engineering Department at Iran University of Science and Technology which Granted me to enroll in M.Sc. I continued studying even harder and graduated in Telecommunication-Systems in Sep 2021. I got the admission from Prof. Marco Di Renzo and joined the laboratory of signals and systems in CentraleSupélec in Feb, 2022.

Short description of project objectives

Recently, Metamaterial surfaces have shown great potential in increasing the spectrum and energy efficiency of wireless communications. Furthermore, they are also expected to assist the integrated sensing and communication (ISAC) by providing better sensing. Utilizing these antennas lead to enhancement of sensing and communication performance in ISAC by offering a finer controllability of the antenna beam pattern. However, new challenges appear that need to be elaborated carefully in order to benefit from this technology. The main objective is to detect different targets while satisfying requirements of communicating with users. There are different metrics for both functions. For instance, for target detection, beam pattern gain, target detection probability and Cramér-Rao Bound (CRB) for target estimation, and for communications, SINR can be used. So far, during the two months that I started my PhD program, I tried to fully understand the problem and state of art developments in this area. My aim is to use specific metamaterial antenna named Reconfigurable holographic surface to solve the problem more efficiently. However, before starting to tackle the problem, it is required to completely obtain a proper model for signal propagation inside the surface.
