Optical theorem and generalized energy conservation for scattering of time-modulated waves
Erik Orvehed Hiltunen, John C. Schotland
We introduce and study a generalized energy conservation relation for scattering of time-modulated waves, where conventional energy conservation does not hold. Based on this relati…

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…
