Terahertz Channel Modeling, Estimation and Localization in RIS‐Assisted Systems
Reconfigurable intelligent surfaces have become a recent intensive research focus. Based on practical applications, channel strategies for RIS‐assisted terahertz wireless communication systems are categorized into three different types: channel modeling, channel estimation, and channel localization.

Homological computations in electromagnetic modeling.
The users of modern design software for electrical appliances can accidentally attempt an analysis of ill-posed design problems, ones with no sensible solution. It is tedious to track down such mistakes manually, but certain topological objects, the homology groups, provide systematic procedures for detection of such mistakes.

Physical reservoir computing (PRC) based on spin wave interference has demonstrated high computational performance, yet room for improvement remains. In this study, we fabricated this concept PRC with eight detectors and evaluated the impact of the number of detectors using a chaotic time series prediction task.
