December 17 to 20, ZJUI Assistant Professor Tan Shurun led a team of ZJUI students to the 42nd PhotonIcs & Electromagnetics Research Symposium (PIERS) in Xiamen. The students team include ZJUI Junior year students Ma Xiaoyu, Tang Zhizhan who major in electrical engineering and doctoral students Feng Zhaoyang of class of 2023. Ma Xiaoyu and Tang Zhizhan presented their work named”An Improved Model For Soil Moisture Content Estimation from GNSS SNR Measurements” which got the attention of the participants with a heated discussion. Feng Zhaoyang’s Paper, "Efficient Characterization of Topological Photonics Using the Broadband Green 's Function”, was selected from more than 1700 article submissions and was awarded a third prize for best paper award.
Two undergraduates of class of 2021 presented their outcomes from the Student Research Training Program of ZJUI, which is guided by Prof. Tan, Their presentation introduced a new use of GNSS satellite signal theory model for Soil Moisture Content Estimation, they think it can be applied and can provide a higher precision of measurement with lower cost in the future. They also told that they will do field measurements and experiments later, to further verify and the develop the model.
A novel method is developed in Feng’s paper to characterize the band diagram and modal fields of gyromagnetic photonic crystals that support topological one-way edge states. The broadband Green's function allows converting the discretized surface integral equation (SIE) into a linear eigenvalue problem of a small size. The broadband Green's function is a hybrid representation of the periodic lattice Green's function that includes an imaginary wavenumber component represented in exponentially decaying spatial series and a reminder in fast converging spectral series. It’s more efficient comparing to the conventional method because of the small condition number and it can get more accurate results while dealing with the periodic structure scattering. The proposed approach is an efficient method to characterize the band diagram and modal fields. This paper is advised by Prof. Tan Shurun. With excellent on-site presentation and the innovative ideas proposed in the paper, Feng won a third prize of Best paper of PIERS from more than 1700 submissions.
PhotonIcs and Electromagnetics Research Symposium( PIERS), also known as Progress in Electromagnetics Research Symposium, provides an international forum for reporting progress and recent advances in the modern development of electromagnetics, photonics and exciting applications. Topics include electromagnetic theory, photonics, plasmonics, metamaterials, antennas, microwave technologies, computational electromagnetics, electromagnetic compatibility, scattering, remote sensing, radars, radiometry, imaging, radiative transfer, inverse problems, quantum electrodynamics, quantum optics, material effects, acoustics, and all other modern developments. PIERS is sponsored by The Electromagnetics Academy. Subsequent PIERS have been held in various cities around the world, including Northern Ireland, Cambridge, Pasadena, Cambridge, Tokyo and etc. It has held for more than 40 times and it became the most prestigious symposium in this areas. Prof. Tan led these ZJUI students for PIERS conference, let them experience the thought collision in international academic conferences and good atmosphere of academic exchange, stimulated the enthusiasm of the students to participate in scientific research, also enhanced the influence of ZJUI.
