Effective Medium Theory for Time-modulated Subwavelength Resonators
Habib Ammari, Jinghao Cao, Erik Orvehed Hiltunen +1
This paper provides a general framework for deriving effective material properties of one-dimensional, time-modulated systems of subwavelength resonators. It applies to subwaveleng…

Energy Balance and Optical Theorem for Time-Modulated Subwavelength Resonator Arrays
Erik Orvehed Hiltunen, Liora Rueff
We study wave propagation through a one-dimensional array of subwavelength resonators with periodically time-modulated material parameters. Focusing on a high-contrast regime, we u…

Space-Time Wave Localisation in Systems of Subwavelength Resonators
Habib Ammari, Erik Orvehed Hiltunen, Liora Rueff
In this paper we study the dynamics of metamaterials composed of high-contrast subwavelength resonators and show the existence of localised modes in such a setting. A crucial assum…
