The time-domain numerical computational methods have extensive applications in the field of computational electromagnetics and related areas. These methods are primarily used for simulating and analyzing the time-domain behavior of electromagnetic fields, including the propagation, scattering, radiation, and interactions of electromagnetic waves. The purpose of this conference is to delve into the current developments of time-domain numerical computational methods and their applications in related fields.It is certain that if there is involvement in semi-classical quantum electromagnetic theory, machine learning, electromagnetic-thermal coupling, and the like, we welcome opportunities to engage in discussions and analysis with new application areas. The aim is to discover new research avenues and better explore and exploit the engineering application value of time-domain numerical computational methods.
