In the podcast episode #14, Prof. Aryan Kaushik, IEEE CTN Senior Editor, chats with Prof. Marco Di Renzo on latest technology of Electromagnetic Signal and Information Theory (ESIT) which sets to unveil the fundamental limits of communication systems moving from first electromagnetic principles, and to develop electromagnetically consistent communication models, signal processing and optimization algorithms. The ESIT field is inherently interdisciplinary and intended to glue research across multiple scientific fields such as including communication and information theory, signal processing, antennas and propagation, electromagnetics, metamaterials, and optics. Within the framework of ESIT, Stacked Intelligent Metasurfaces (SIM) is one of the emerging next generation technologies to enable smart radio environment. Tune in to our podcast and hear from experts on these topics. Led by both the professors in conversation, you can also follow the new IEEE ComSoc ETI on ESIT at https://www.comsoc.org/about/committees/emerging-technologies-initiatives/electromagnetic-signal-and-information-theory.
