... model (FOM) and reduced-order model (ROM), this approach ensures that the essential dynamical properties are preserved. The ultimate goal is to create a reduced order model that is suitable for rapid simulations, control and analysis in electromagnetic applications, such as waveguides, which involve...

...Ayoub Bellouch; Amine El Alami; Frederic Messine; Nathalie Raveu Purpose The purpose of this sudy is to provide a complete optimization-based methodology to design waveguides with metamaterial walls. The present methodology is based on optimization. Indeed, the inverse problems of design...
