The 11th International Conference on Computation in Electromagnetics will be held from April 11th to 14th, 2023 in Cannes, France. CEM2023 is the next in a series of conferences on Computation in Electromagnetics extending back more than 25 years. CEM 2023 will be conducting conferences and exhibitions to provide a forum for the discussion of problems, solutions, research, and development spanning the spectrum of electromagnetics, focusing on the numerical modeling techniques and applications from “DC to Daylight” (and beyond). The conference will conduct a number of thematic sessions—each based on interactive poster presentations. The session starts with an invited “scene setting” introduction, followed by each author in that session providing a “one minute, one slide” overview before opening the interactive session itself. This allows more detailed and tailored conversations than are possible in traditional “oral” sessions.
